0.75
0.8
1.25
1.5

Answer 1

y=mx
10=m(8)
m=1.25
the constant of proportionality is 1.25

Answer 2

Yes really simple, y is the bottom  10 15 and 25 well in a graph y is on the top so put y on top of x and divide. SO 10 divided by 8 15 divided by 12 and 25 divided by 20 which all equal 1.25! Now just because I'm only a helping hand doesn't mean I dont know my math! Hope I helped
