Choose the point-slope form of the equation below that represents the line that passes through the point (6, −3) and has a slope of one half.
y − 6 = one half(x + 3)
y = one halfx − 6
y + 3 = one half(x − 6)
x − 2y = 12

Choose the point-slope form of the equation below that represents the line that passes through the point (6, −3) and has a slope of one half.
y − 6 = one half(x + 3)
y = one halfx − 6
y + 3 = one half(x − 6)
x − 2y = 12

I dont understand this at all...pleas help me....

amorfide · Answer

standard point-slope form is y=mx+c
m is the slope
slope is 1/2

y=1/2x + c
(6,-3)
x=6, y=-3

-3=6/2 + c

work out c
then sub c into y=1/2x + c

firechild17 · Answer

I thought the point-slope form was y=mx+b @amorfide

amorfide · Answer

a, b, c, d, e take your pick, they are just constants, in england we use c. Sorry, if you use b, just use b instead of c

y=mx+b
y=1/2x + b

amorfide · Answer

solve for b

firechild17 · Answer

ok

firechild17 · Answer

so its C?

amorfide · Answer

b=-6
y=halfx - 6
so it would be B
