Question

What is the slope of (-1,-1) and (1,5)?? Please help me!!!

Answer 1

The slope of (-1,-1) and (1,5) is three

Answer 2

Slope is 3.

Explanation:

Slope is change in y to change in x:

`\displaystyle{\text{slope} = (\Delta y)/(\Delta x)}\\\\\displaystyle{\text{slope} = (y_2-y_1)/(x_2-x_1)}`

In mathematics, slope is generally declared as "m" variable.

Also, we are given two coordinate points. Let
`x_1` be -1,
`x_2` be 1,
`y_1` be -1 and
`y_2` be 5.

Therefore:

`\displaystyle{m = (5-\left(-1\right))/(1-\left(-1\right))}\\\\\displaystyle{m=(5+1)/(1+1)}\\\\\displaystyle{m=(6)/(2)}\\\\\displaystyle{m=3}`

Therefore, the slope is 3.
