Question

Which expression can be used to find the slope of a line containing the points (–3, 2) and (7, –1)?

Answer 1

m=y2-y1/x2-x1
m=-1-2/7-(-3)
m= -3/10

Answer 2

Formula:

$\text {Slope = }\dfrac{Y_2-Y_1}{X_2-X_1}$

Given the two points (-3,2) and (7,-1)

(X1, Y1) = (-3, 2)

X2 , Y2) = (7, -1)

Find Slope:

$\text {Slope = }\dfrac{-1-2}{7-(-3)}$

$\text {Slope = }\dfrac{-3}{10}$

Answer: The slope is -3/10
