Question

What is the slope of the line through (-1, -7) and (3,9)?

Choose 1 answer:
A
B
4

Answer 1

m = 4

Explanation:

We are asked to find the slope of the line that passes through the following two points:

(-1,-7) and (3,9)

Use the formula:

`\sf{m=\cfrac{y_2-y_1}{x_2-x_1}}`

Substitute the values:

`\sf{m=\cfrac{9-(-7)}{3-(-1)}}`

`\sf{m=\cfrac{9+7}{3+1}}`

`\sf{m=\cfrac{16}{4}}`

`\sf{m=4}`
