1 Math A Eleentar Algebra Stud Guide for Ea Ea is scheduled for Wednesda, Noveber 9 th. You a use a " " note card (both sides) and a scientific calculator. You are epected to know (or have written on our note card) an forulas ou a need. Think about an forulas ou needed for hoework. For eaple: slope forula, slope-intercept forula, point-slope forula, etc... For Ea ou will need to be able to:. Plot points in the Cartesian coordinate sste, find issing coordinates, and deterine if a point is on a line b deterining whether an ordered pair is a solution to the equation... Graph linear equations b plotting points. You ust plot at least points... Graph linear equations that go through the origin.. a * lines through the origin have the for a b or b. Graph linear equations using the and intercept. Must also plot a rd point used as a check point. Reeber to write the intercepts as points.. * For -intercept: set =, solve for ; (,) * For -intercept: set =, solve for ; (,). Graph horizontal lines and vertical lines.. *The equation =constant is a horizontal line *The equation =constant is a vertical line 6. Deterine the equation of a horizontal or vertical line.. 7. Find the slope of a line.. * Given (, ) and (, ), use forula to find slope, rise * Given a graph of the line, use or state that the slope is undefined. run 8. Graph a line, given a point and the slope. Plot at least points.. 9. Given two slopes, deterine if the two lines are parallel, perpendicular, or neither.. * Parallel lines if * Perpendicular lines if. Write a linear equation in slope-intercept for, b... Graph a linear equation using the slope,, and intercept, (, b). Plot at least points... Deterine the equation of a line given a graph. Write the answer in slope intercept for... Write the equation of the line given a point on the line, ) and the slope of the line.. ( * To write an equation given a point and a slope: Given, ) and use ), then solve for to get into b for. ( (. Write the equation of the line given two points on a line, ) and, ).. ( * To write an equation given points:. Given (, ) and (, ) use to calculate,. Then use ), then solve for to get into b for. ( (. Graph linear inequalities. Use a test point to deterine the shaded region (the solution).. * If or, shade above the line. * For or use and open dots * If or, shade below the line. * For or use and closed dots
