You have to multiply both of the numbers in the parenthesis and then multiply them again them
Ex: 4 x 4 = 16
(2x2) x (2x2)
4 x 4 =16
-- these are called same side exterior angles, which means they are supplementary.
x + 9 + 2x + 6 = 180
3x + 15 = 180
3x = 165
x = 55
so, option B.
Answer: y = x -1
reasoning: the slope is 1 because the rise/run = 1/1, which simplifies to 1.
the y intercept is -1 because the line passes through the y axis at -1.
hope this helps!
The answer is B because it’s not a straight line and x can not have an exponent of 2 bc it will make it nonlinear
