Which ratio does NOT form a proportion with 5/8? A 20/32 B 100/160 C 45/56 D 10/16

A.
y-intercept is where the line crosses the y axis
it seems to cross at y=4

B. seems to be linear, so
y=mx+b is equation
m=slope
b=y intercept
we know that yintercept=4=b

slope=rise/run=z/t
it for every z units it goes up, it goes to the right t units
seems to go up 17 for every 11 units it goes to the right
so slope=17/11

equation is
so predict that after 13 months (x=13), we have y=(17/11)13+4=221/11+4≈24 games won
