Help would be greatly appreciated:)

Slope intercept form is defined as y=mx+b

Defining terms
Y is any y value on the the line
X is any x value in the line
M is the slope
B is the y intercept (0,b)

The problem is essentially asking you to find the value for b

To do this, we sub in the values we know

So, put the slope value in the formula

Y=(-1/4)x+b

From there, you can substitute the coordinate values provided and solve for b

-5=(-1/4)(-5)+b
-5=(5/4)+b
-6.25=b

So now we can rewrite the whole equation as

Y=(-1/4)x-6.25

Hope that helped!
