# How do you write the equation in slope intercept form given (1,-3) with x-intercept = -1?

##### 1 Answer

#### Explanation:

Explanation

Explanation:

In

m = the slope think m = mountain slope

b = the y-intercept think b = beginning starting point.

m ; the slope = the change in y divided by the change in x

Substitute -3 for

Substitute 1 for

m =

Now, to find the y-intercept remember

So one point is ( 0, b) and a second point is ( 1,-3)

multiplying both sides by -1 gives

subtracting -3 from both sides gives
