What is an equation of the line that passes through the points (8,-8) and (1,6)

Answer 1

The equation of a line is y = mx + b, where m is the slope and b is the y-intercept.

First to find the slope of the line, use the equation (y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are two points that the line passes through. You are given (x1,y1) as (8,-8) and (x2,y2) as (1,6).

Second, to find the y-intercept, substitute x1 for x and y1 for y and m for the determined slope in the equation of a line to solve for b, the y-intercept.
