Find the value of k in:
4x+=+k-3y if the graph of this equation has a y-intercept of (0, -8)
Since the graph intercepts the y-axis at (0, -8) then these coordinates must satify the given equation, so we'll substitute x = 0 and y = -8 and solve for k.
4%280%29+=+k-3%28-8%29
0+=+k-%28-24%29
0+=+k%2B24 Subtract 24 from both sides.
