Question

What is the slope of the line that passes through the points (–1, 13) and (4,-2)? A. -1/3 B. 3 C. the slope is undefined D. -3

Answer 1

To calculate slope (which can be represented as the variable, m), we must use the equation for slope...

m = Δy/Δx = (y-$y_{1}$)/(x-$x_{1}$)

We are given two points, each in format (x, y)

m = (13 - (-2)) / (-1 - 4) = 15 / -5 = -3 (D)
