Y - 11 = 3(x +4)

Write this In slope intercept form

Y=3x+15. You need to use distributive property and multiply 3 by x and by 4 which equals to 3x + 4 then add to both sides so it cancels out and gets y by itself and 11 + 4 = 14 so it comes out to be y=3x+15

Coterminal angles are angles with the same terminal side.

When we have an angle A, the coterminal angles can be written as:

A + k*(360°)

where k can be any integer number. (Notice that when we have k = 0, means that A is coterminal with itself)

Then the set of all the coterminal angles to -225° is:

{-225° + k*360°I k ∈ Z}

where Z is the set of integer numbers.
