Question

Graph the line that passes through the points (1, -2) and (-1,-6) and

determine the equation of the line.

Answer 1

y = 2x - 4

Explanation:

The equation is y = mx + b

m = The slope

b = y-intercept

To find the slope, we look for the rise/run or (y2 - y1) / (x2 - x1)

The slope here is 2, and the y-intercept is located at (0,-4), so the equation is

y = 2x - 4
