Question

What is the value of y for the line that has a slope of 1 and goes through the points (-4, y) and (-2, 8)?

Answer 1

y = 6

Explanation:

To write the equation of a line, calculate the slope between points (-4,y) and (-2,8). Substitute m = 1 and solve for y.

`m = (y_2-y_1)/(x_2-x_1)\\\\ 1 = (y-8)/(-4--2)\\\\ 1 =(y-8)/(-2)\\\\-2=y-8\\\\6=y`
