Answer:
y=3x
Step-by-step explanation:
y=kx, where k is constant
3y, 1x...so 3y = 1x
check: looking at the graph at 4.5y, 1.5x where y and x intersect...
4.5=3(1.5)
3 x 1.5 = 4.5

= 21
First, simplify

to

/ Your problem should look like:

= 21
Second, multiply both sides by 8. / Your problem should look like: -7k = 167
Third, divide both sides by -7. / Your problem should look like: k =
Fourth, simplify

to

/ Your problem should look like: k =
Fifth, simplify

to 24. / Your problem should look like: k = -24
Answer:
k = -24
