Question 684139
x intercept is (-3, 0)
y intercept is (0, k)
and 
point (5, 8)
...
Use x intercept and point to find slope
{{{(0-8)/(-3-5) = -8/-8 = 1}}}
...
Use y intercept and x intercept and slope to solve for k
{{{(0-k)/(-3-0) = 1}}}
{{{-k/-3 = 1}}}
...
-k = 1(-3)
-k = -3
{{{highlight_green(k = 3)}}}
