If the graph of a linear equation is translated 4 units down, which statement best describes the change to the equation? A. The y-intercept of the equation is decreased by 4.
B. The y-intercept of the equation is increased by 4.
C. The slope is changed by a factor of −4
D. The slope is changed by a factor of 4.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
