So we know that point-slope form is as follows:

y-y_(1)=m(x-x_(1))

The points (
x_(1) and
y_(1) correspond to the point given and m is representing the slope. So we plug in what the question gives us:

y-(8)=-3(x-1) <------ Point-slope form

Now we can take this form and simplify to give us the slop-intercept form:

y-8=-3(x-1)

y-8=-3x+3

y=-3x+11 <----- Slope-intercept form
