Question

How would I find the slope intercept form for this problem.  The line has an x-intercept of -5 and a y-intercept of -8?

We know, based on the information, that we have 2 points. (-5,0) and (0,8)
We already know that in slope intercept form b is known, which is -8. 
So far we have $$y=mx-8$$
Now, to get the slope we must use the slope formula, or:
$$\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }$$
Plug in the 2 points into this equation.
$$\frac{ -8-0 }{ 0+5 }$$
Now we simplify this to get: -1.6=m
Therefore:
$$y=-1.6x-8$$
