Question

Given the equation y - 3 = 1/2(x + 6) in point-slope form, identify the equation of the same line in standard form.

A. x - 2y = -12

B. y = 1/2x

C. y = 1/2x + 6

D. y = 1/2x + 9

Answer 2

y - 3 = 1/2(x + 6) -- distribute through the parenthesis
y - 3 = 1/2x + 3 -- add 3 to both sides
y = 1/2x + 3 + 3
y = 1/2x + 12 --- multiply everything by 2
2y = x + 12 -- subtract x from both sides
-x + 2y = 12 -- multiply by -1 to make x positive
x - 2y = -12 <== standard form

Answer 3

well...I feel stupid...standard form is Ax + By = C...there is only one answer in this form

Answer 4

so A ?

Answer 5

yep..its A....you wouldn't have even had to work it out...lol

Answer 6
