write a direct variation equation for (24, -8)

Question

write a direct variation equation for (24, -8) and graph 3 points

Answer 1

General form of direction variation equation y = kx, where k is the variation constant

substitute (24,-8) for x and y in the above equation to solve for variation constant k

-8 = k24

k = -1/3

so y = -1/3x

substitute three values for x, say 0, 3, 6 in above equation and get y (0,-1, -2) to get three points to plot (0,0),(3,-1),(6,-2).

Answer 2

-8 = 24k

You graph.
