Question

Determine the slope of the line that passes through the points (-2, 5) (1, -7)

Answer 1

Answer:

slope is -4

Step-by-step explanation:

Find slope which is also referred to as m:

m = (y₂ - y₁) / (X₂ - X₁)

   = (-7 - 5) / (1 - (-2)

   = -12 / 3

m = -4

Not asked in question but if you want to find equation for the line:

Find b using any one of the two provided coordinates. Let's use (-2, 5).

y = mx + b

5 = -4(-2) + b

5 = 8 + b

b = -3

Use m and b to make equation.

y = mx + b

y = -4x - 3

Answer 2

Answer:

• -4

Step-by-step explanation:

Given points

• (-2, 5) (1, -7)

Use slope formula to find the slope

• m = (y2 - y1)/(x2 - x1)
• m = (-7 -5)/(1 + 2) = -12/3 = -4

Slope is -4
