Find the coordinates of the mid-point of x and y intercepts of the line 2y = 4x - 8
A.
(2, 0)
B.
(1, -2)
C.
(-1, -2)
D.
(1, 2)
Correct Answer: (1, -2)
Explanation
2y = 4x - 8 ⟹ y = 2x - 4. When x = 0, y = -4. When y = 0, x = 2. The midpoint between (0, -4) and (2, 0) = ((0+2)/2,(−4+0)/2) = (1,−2)
2y = 4x - 8 ⟹ y = 2x - 4. When x = 0, y = -4. When y = 0, x = 2. The midpoint between (0, -4) and (2, 0) = ((0+2)/2,(−4+0)/2) = (1,−2)THIS WEEK's
