Question

The graph of a proportional relationship passes through (12,16) and (1,y). find y​

Answer 1

4/3

Explanation:

A proportional relationship is a relationship that crosses through the origin or (0,0). This means the slope of the line can be found by subtracting the points (12,16) and (0,0) in the slope formula.

`m = (y_2-y_1)/(x_2-x_1) =(16-0)/(12-0)= (16)/(12)=(4)/(3)`

So the slope is 4/3 and must be the value between any two points on the line.

This means the function moves from (0,0) to (1, 4/3).
