Question

What is the slope of the line passing through the points (–1, 3) and (4, –7)?

A. 2


B. 3/4


C. -4/3


D. -2

Answer 1

(-1,3) and (4,-7)
x1 = -1
x2 = 3
y1 = 4
y2 = -7
slope(m) = y2 - y1/x2 - x1

Answer 2

Thats easy enough. Simply use the Gradient formula:
\[m=\frac{y_2-y_1}{x_2-x_1}\]

Where:
\((x_1,y_1) = (–1, 3)\)
\((x_2,y_2) = (4, –7)\)

Substitute, and solve :)
\[m=\frac{y_2-y_1}{x_2-x_1}\]
\[m=\frac{-7-3}{4--1}\]

Answer 3

Is D correct
