The equation shows the relationship between x and y:

y = - 5x + 8

What is the slope of the equation?

-8

-5

3

8

Y = mx + b is called the slope-intercept form

It is called that for a reason.

y = mx + b

m is the slope

b is the y-intercept

The equation you have is:

y = - 5x + 8

Therefore,

-5 is the slope

8 is the y-intercept

So the slope of the equation y = - 5x + 8 is - 5

The slope is - 5 because it has an x behind it
