Question

write an equation of the line, in slope intercept form, that passes through the given point and has the given slope. point:(8,-8), slope:3

Answer 1

If m equals 3, and we have a y and x value of 8 and -8, all we have to do is solve for b.

-8 = 3(8) + b
Multiply 8 and 3.
-8 = 24 + b
Subtract 24 from both sides to isolate b.
-32 = b

Your equation would look like this:

y = 3x - 32
