Question

Choose the correct slope of the line that passes through the points (1, −3) and (3, −5).

Answer Choices
A. 1
B. -1
C. 0
D. 1/2

Answer 1

B

Explanation:

Calculate the slope m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (1, - 3) and (x₂, y₂ ) = (3, - 5)

m =
`(-5+3)/(3-1)` =
`(-2)/(2)` = - 1 → B

Answer 2

B. -1

Explanation:

Use the slope formula to find the slope m .
