Question

What is the slope of the line that passes through the pair of points (5,-2) (0,-1)

Answer 1

-(1/5)

Explanation:

The slope is the Rise/Run between the two points (5,-2) and (0,-1):

Rise = -1 - (-2) = 1

Run = 0 - 5 = -5

Slope = Rise/Run = 1/-5 or -(1/5)

Point (0,-1) tells us that the y-intercept, b, is -1, so the full equation is:

y = -(1/5)x - 1
