Question

What is the slope of the line joining (-4,7) and (-5,0)?

Answer 1

7

Explanation:

First, take (-4,7). That is your x1 and y1 numbers. Do the same thing for (-5,0) except, it will be x2 and y2.

Second, subtract y1 from y2 all over x1 from x2

EX: 0-7 m=7

-5-(-4)

Answer 2

slope = 7

Explanation:

To calculate the slope m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 7) and (x₂, y₂ ) = (- 5, 0)

m =
`(0-7)/(-5+4)` =
`(-7)/(-1)` = 7
