Question

Write the equation of the line that passes through the points (-2,1) and (0,8)

Answer 1

The equation of the line is y = 7/2x + 8

Explanation:

The equation of the line is in the form y = mx + b, where m is the slope and b is the y-intercept. To find m, you just have to subtract the two points from each other.

`(8 - 1)/(0 - (-2))` = 7/2

The y - intercept always has an x-value of 0, so the y-intercept would be 8.

So, the equation is y = 7/2x + 8
