Answers

Answer 1

Answer: Since the y in the first equation is positive and the y in the second equation is negative the t’s would completely cancel out. Y is like saying 1y and negative y is like saying -1y. If you add 1 to -1 you get 0 n

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

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