Answer 2

I know y=mx+b. Any help?

Answer 3

@Data_LG2 This is my last question

Answer 4

i think it's y = 2x + 3

Answer 5

The choices are:

y – 7 = 2x + 5
y = 2x
y = 2x + 3
y = 2x – 3

Answer 6

let's if you're right...

\(\sf (Y-Y_1)=m(X-X_1)\)

Find m=2
plug the points into the equation:
\(\sf (Y-7)=2(X-5)\\Y=2x-10+7\\Y=2x-3\)

confirm using the other point:
\(\sf (Y+7)=2(X+2)\\Y=2x+4-7\\Y=2x-3\)

Answer 7

It's 'minus 3'

thanks for all your help! @Data_LG2
