Question

A linear function is graphed below.

(-1, 4)
(5, -5)

What is the slope of this graphed line?

Answer 1

Explanation:

find the slope m by using the slope formula

m = (y2 - y1) / (x2 - x1)

Point1 = ( -1,4) where it takes the form (x1,y1)

Point2 =(5, -5) where it takes the form (x2,y2)

notice the form is important

m = (-5 -4) / (5 - (-1))

m = -9 / ( 5 +1 )

m = -9 / 6

m = - 3/2

Answer 2

`-1(1)/(2)`

Explanation:

We have two coordinate points and are asked to find a slope.

When finding slope, we can use the formula listed :

`(y^2-y^1)/(x^2-x^1)}`

To understand what the variables are, you can take this :

`(x^1,y^1)`

`(x^2,y^2)`

Substitute the points :

`(-1,4)`

`(5,-5)`

Now substitute it into the formula :

`(-5-4)/(5-(-1))`

`(-3)/(2)`

`-1(1)/(2)`
