Answer 2

@robtobey

Answer 3

I think the first one is B

Answer 4

@.Sam.

Answer 5

no, it is not B

Answer 6

\[y-y_1=m(x-x_1)\] is the "point - slope" form
in your case \(x_1=7,y_1=-2, m=-3\)

Answer 7

Then it'd have to be D right?

Answer 8

make a direct substitution in to the formula and get
\[y-(-2)=-3(x-7)\]
which you would then rewrite as
\[y+2=-3(x-7)\]

Answer 9

Ah too fast @satellite73 !

Answer 10

you can splain the next one

Answer 11

Ah I see now, so for the 2nd one I think it's A but I could be completely wrong again... @.Sam. @satellite73

Answer 12

i lied it's d

Answer 13

If its parallel, then the gradient is the same, so, we've got (4,-6) and m=-1/2, then use the point slope form
\[y-y_1=m(x-x_1)\]
\[y-(-6)=-\frac{1}{2}(x-4)\]
\[y=-\frac{1}{2}x-4\]

Answer 14

@haleycoulter Yes you've got it
