Question

I'm lost on this please help

Answer 1

y+7=2(x+10)

Explanation:

we find the slope

`(y2-y2)/(x2-x1) \\(9-(-7))/(-2)-(-10)\\(9+7)/(-2+10)\\16/8\\2\\y-y1=m(x-x1)\\y-(-7)=2(x-(-10)\\y+7=2(x+10)\\`

you can simplify but its already in point slope form

but here it is if you are curious and want to double check it is

y=2x+13

we can also check our work

-7=2(-10)+13

-7=-7
