Question

Which point lies on the line described by the equation below?. . y + 8 = 4(x - 5). . A.(5, -8). B.(4, -8). C.(-5, -8). D.(5, 8). E.(4, 5). F.(5, 0)

Answer 1

One way of knowing the answer is by substituting the values and see if it agrees with the equation.

y + 8 = 4(x - 5)

A.(5, -8).
-8 + 8 = 4(5 - 5) 
0 = 0 ----> EQUAL and THE CORRECT ANSWER

B.(4, -8).
-8 + 8 = 4(4 - 5) 
0 = -4 ----> NOT EQUAL

C.(-5, -8).
-8 + 8 = 4(-5 - 5) 
0 = -40 ----> NOT EQUAL

D.(5, 8).
8 + 8 = 4(5 - 5) 
16 = 0 ----> NOT EQUAL

E.(4, 5).
5 + 8 = 4(4 - 5) 
13 = -4 ----> NOT EQUAL

F.(5, 0)
0 + 8 = 4(5 - 5) 
8 = 0 ----> NOT EQUAL
