Question

Help!!! ---- The graph of a function is a line that passes through the points (1,4), (3,8), and (6,y). What is the value of y?

Answer 1

y = 14

Explanation:

First find the slope of the line. To find the slope of the line, use the slope formula:

`m = (y_2-y_1)/(x_2-x_1) = (8-4)/(3-1) =(4)/(2)=2`

The slope of the line is 2.

Repeat this same process instead with points (1,4) and (6,y). Substitute m = 2.

`2 = (y-4)/(6-1) \\\\ 2=(y-4)/(5)\\\\ 10=y-4\\\\14b= y`

So y = 14.
