The rate of change of function f is the same from x = -2 to x = 1 as it is from x = 1 to x = 4. Function f is a(n) function.

A) Quadratic
B) Linear
C) Exponential

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
