1 Summer Packet Geometry PAP IMPORTANT INSTRUCTIONS FOR STUDENTS!!! We understand that students come to Geometry with different strengths and needs. For this reason, students have options for completing the packet and getting assistance! Students should try to answer all the questions; you must show all work. The purpose of this packet is to allow students to show what they know on certain concepts while informing the teacher of concepts that may need to be reviewed with students after school starts. Video Tutorials will be posted on Mr. J. Schroeder Website under the summer packet tutorial page. Need face-to-face help with packet? Come to WHS on August th between 1-pm! WHS Geometry teacher(s) will be on hand to give you assistance! There will be an assessment over this material on or before September 7, 018. Finally, honor and integrity is at the heart of a Westside Wolf! Smart wolves never cheat. You are only hurting yourself by attempting to copy someone else s work. This packet is to help you be ready for Geometry and help your teachers know what you can do. All eisting and new students who are enrolled at WHS on or before August 17 th, must submit their summer packet to their math teacher no later than Tuesday, September, 018. Students who enrolled at Westside High School on or after August th, must submit their summer packet within two weeks of their enrollment date at Westside. Now! Get Ready, Get Set, and Do Your Best!

2 A. Find the slope of the line containing each pair of points. 5,0 and 6,8., and 6,., and 9, 7 B. Find the slope of each line.. y y y 7 C. Find the equation of the line with the given slope through the given point. Write the answer in slope-intercept form. 8. m ;, 9. m ;,7 10. m ;, 1 D.

Factor each of the following polynomials a 1a P. Solve each quadratic equation using the square root property Q. Solve each quadratic equation using factoring p 16p m m 1 5. t 9t

5 R. Use Pythagorean Theorem to find the missing side of the right triangles. If c is the measure of the hypotenuse of a right triangle, find each missing measure. Round to the nearest hundredth if necessary. It is better if you can leave as a simplified radical like in Section S. (Simplified radicals will be the type of answers used in Geometry) a 5, b 1, c?. a 6, b, c?. a 5, b 8, c?. a?, b 10, c 11 S. Simplify the following radicals (you answer will not be a decimal) T Simplify each problem using eponent rules 6 5 =. c c c = =. a 5a = 5. y y = 6. cd c cd 7. 5a = 8. 6 = = U Solve each equation. c 1) 6 ) 15 ) 7 1 ) 5) 1 5 6) 5t t 16 7) 7 h 11 8) 10t 8 5 9) 1 y 1 y

6 1 A. Slope formula m Eamples for Summer Packet Westside High School y y 5 8 E: 1, and,5 m 1 1 B. Slope intercept formula: y 1 Eample: y 1 y y m b slope y-intercept Slope is y-intercept is 0, Special Cases: Horizontal lines are Vertical line y a number slope is 0 a number slope is No slope C. Point slope formula: y y1 m ( 1 ) Use point slope when you have a point and slope and y of slope of want an equation of a line in slope intercept. Solve ordered ordered pair pair the equation for y once the point and slope are plugged in. Eample: y ( ) ( 6) plug in ordered pair and slope y Distribute y Solve for y, now equation is in slope intercept form D. Use eamples from A to find slope. Take slope and one of the points and plug into point slope, and use eample from C. Once equation is in slope intercept, get and y on one side and multiply by common denominator of and y, so that there is not any fractions. Eample: (, ) and (6, 0) 0 m 6 y ( ) ( ) y y y y y 1 E. Use information from A,B,C,D to figure out E. F. Use information from A,B,C,D to figure out F. G. Use information from A,B,C,D to figure out G.

7 H. Graph from point slope, y y m ( ) 1 1 y of slope of ordered ordered pair pair y ( 1) ( 1, ) m Equation Pull out point and slope from equation. Plot point Use slope to plot other points Draw line Slope is rise up or down up and 1right run right or left 1 I. Graphing from slope intercept, y m b slope y-intercept 1 y Equation 1 m (0,) Pull out slope and y-intercept Graph y-intercept Use slope to graph other points J. Graphing from standard form, A By C Take equation solve for slope intercept form, then use the steps from I. K. PEMDAS = Parentheses, Eponents, Multiplication/Division, Add/Subtract from left to right L. The five steps to solving an equation are: Get rid of parentheses Simplify the left side and the right side of the equation as much as possible, i.e. combine any and all like terms Get the variable term on just one side Get the variable term by itself Solve for the variable. Remember, you always use the opposite operation to get rid of something. When problems have fractions try clearing the fractions by multiplying by the least common denominator and the problem will be easier to solve.
