Question

Without drawing the graph of the function y=1.2x−7, see if the graph passes through points: (100; 113)

Answer 1

(100,113) is on the graph of y = 1.2x -7

Explanation:

y=1.2x−7

Substitute the point in and see if the equation is true

113 = 1.2 (100) -7

113 =120 - 7

113 = 113

This is true, so the point is on the graph
