Question

Which of the following equations is equivalent to y - 3x = 4 ?

A. y-10 = 3(x - 2)
B. y = -3x+4
C. y-10 = 3(x - 1)
D. y - 7 = 3(x - 1)

Answer 1

A and D

Explanation:

A:

y - 10 = 3(x - 2)

y - 10 = 3x - 6

y - 10 (+ 10) = 3x - 6 (+ 10)

y = 3x + 4

y (- 3x) = 3x (- 3x) + 4

y - 3x = 4

D:

y - 7 = 3(x - 1)

y - 7 = 3x - 3

y - 7 (+ 7) = 3x - 3 (+ 7)

y = 3x + 4

y (- 3x) = 3x (- 3x) + 4

y - 3x = 4

Answer 2

A or d both are correct
