Aline passes through the point (-8,-5) and has a slope of 5/4. write an equation in slope-intercept form for this line

Slope- intercept form:

y= mx+b

Where x and y are the points, m is the slope, and b is the y-intercept.

Plug in the points to find the y-intercept.

-5= 5/4(-8)+b

Solve.

-5= 2.25(-8)+b

Combine like terms.

-5=-18+b

Add 18 on both sides.

13= b

Now you have the y-intercept. Plug in every point except the x and y, because you wouldn't be able to graph it if you had just numbers. (not that you have to; that is just the correct form)

y=5/4x+13

I hope this helps!
