Answer:
If x varies directly as y, then x=ky. y=5 and x=2.5 are substituted into x=ky to find k.
2.5=5k
k=2.5/5
k=5.
K =5 is substituted in x=ky to find y where x is 10.
x=5y
10=5y
y=10/2
y=2
Answer:
Slope = -2/2 = -1
x-intercept = 6/1 = 6
y-intercept = 6/1 = 6
I wasn't sure what you really were asking for, so I did slope, x, and y.
