You can put this solution on YOUR website!
x intercept is (-3, 0)
y intercept is (0, k)
and
point (5, 8)
...
Use x intercept and point to find slope
%280-8%29%2F%28-3-5%29+=+-8%2F-8+=+1
...
Use y intercept and x intercept and slope to solve for k
%280-k%29%2F%28-3-0%29+=+1
-k%2F-3+=+1
...
-k = 1(-3)
-k = -3
highlight_green%28k+=+3%29
