Answer:

The slope of the line is [tex]-\frac{3}{7}[/tex] ⇒ B

Step-by-step explanation:

Let us revise the rule of the slope

The rule of the slope of the line is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

  • (x1, y1) and (x2, y2) are two points lie on the line

∵ The line passes through the point (-3, 1) and point (4, -2)

→ That means one of them is (x1, y1) and the other is (x2, y2)

x1 = -3 and y1 = 1

x2 = 4 and y2 = -2

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{-2-1}{4--3}[/tex] = [tex]\frac{-3}{4+3}[/tex]

m = [tex]-\frac{3}{7}[/tex]

The slope of the line is [tex]-\frac{3}{7}[/tex]
