mxddi3 · Answer

so we do this with the point-slope formula of 
$$y-y1=m(x-x1)$$

m, the slope, in this case is -3
and we have (-3,-5) 
we label the ordered pair as x1 and y1.

do you follow so far?

Yes

leilanithomas2024 · Answer

Because the formula to a slope is y2-y1/x2-x1 am i right? @mxddi3

mxddi3 · Answer

ok good.

now, since it's y-y1=m(x-x1 
and we are given the slope of 3, our new equation is :
$$y-(-5)=3(x- [-3]) $$

ok, now, can you simplify this or do you need help?
