Question

What is the slope ( it has a slope of -2) (it has a slope of -1) (it has a slope of 2)

Answer 1

slope = - 2

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = ( - 1, 2) ← 2 points on the line

m =
`(2-0)/(-1-0)` =
`(2)/(-1)` = - 2

Answer 2

`slope = -2`

Explanation:

Step 1: Determine two points

We need to take two points off of the equation that is used in thsi graph and we can see that we have (0, 0) and (-1, 2)

Step 2: Determine the slope

`m = (y_2 - y_1)/(x_2 - x_1)`

`m = (2 - 0)/(-1 - 0)`

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

`m = -2`

Answer:
`slope = -2`
