Which of the following has a graph that is a straight line? equation 1: y = 2x + 7 equation 2: y^2 = x − 1 equation 3: y = 2x^2+ 4 equation 4: y = 3x^3

the answer is 1: y = 2x + 7

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
