Question

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

Answer 1

Answer:

The graph of the function passes through the point (100; 113).

Step-by-step explanation:

In order to calculate if the graph of the function passes through the point or not, we need to insert the point's coordinates in the function and check if the equation is valid or not, if it is, then the graph passes through them.

$y(x) = 1.2*x - 7\\y(100) = 1.2*100 - 7\\y(100) = 120 - 7 \\y(100) = 113$

Which is equal to the "y" coordinate of the point, therefore the graph of the function passes through the point (100;113).
