?

anonymous · Answer

I know the standard Ax+By=c. I just don't know what to do with it

anonymous · Answer

The slope is already given so you just need to put it in point slope form. That is
y-y1=m(x-x1)
We know the slope is 7 so we put that in, and we have the point (1,-3) so we put that in. We now have
y+3=7(x-1)
Now we distribute 7 on the right side. Do you know how to do that?

ok you know the slope is 7 and it goes through the pt (1,-3). now plug these into y=mx+b|dw:1386901994194:dw| i made an error with the answer i told you before the equation is y=7x-10
