1 ? Name 1. Essential Question Graph and Analze Relationships How can ou write and graph ordered pairs in a coordinate grid using number patterns? Geometr and Measurement..C Also..C MATHEMATICAL PROCESSES.1.A,.1.B,.1.D Unlock the Problem Sasha is making hot cocoa for a part. For each mug of cocoa, he uses tablespoons of cocoa mi. If Sasha makes 9 mugs of cocoa, how man tablespoons of the cocoa mi will he use? STEP 1 Use the rule to make an input/output table. Input Mug(s) 1 Output Cocoa Mi (tbsp) STEP Write the related pairs of data as ordered pairs. _(1, ) STEP Plot and label the ordered pairs in the coordinate grid. Use the pattern to write an ordered pair for the number of tablespoons of the cocoa mi needed for 9 mugs of cocoa. Plot the point in the coordinate grid. _ So, Sasha will need _ tablespoons of the cocoa mi to make 9 mugs of cocoa How can ou use the pattern in the coordinate grid to decide if our answer is reasonable?
