-2 = (-2)(2)
Bettr try again.
#2 Nope. At least check your guess by plugging in the point. You said
-3/2x-1
If (2,-1) is on that line, then
(-3/2)(2)-1 = -1
Nope.
#3 Nope. x=-3 is a vertical line. A vertical line through (4,2) is not 2x+4, which has a slope of 2. It would be x=4, which is not a choice given. Typo?
#4
y = 1/2 x - 1 has slope 1/2
So, we want a line with slope -2
That would be
y-3 = -2(x+2)
y = -2x-1
Good work on that one
#5 we want slope -1/2
y-0 = (-1/2)(x-5)
y = -1/2 x + 5/2
