Curt because if his time was 8/9 of Ian's time then that means he ran the mile in a fraction of Ian's time, so he finished the mile quicker. Curt ran faster.
Answer:
$160,000 to $220,000 = 37.5% increase
Step-by-step explanation:
First find your slope! by doing
y2-y1/x2-x1
in this case it would be
2-(-3)/-1-(-6)
It would give you 5/5 which would reduce to 1 meaning your slope equals 1
with your slope now you should use the point slope formula y-y1=m(x-x1)
i’m going to use the point (-1,2) so the equation would be
y-2=1(x-(-1))
simplifying that you would get
y-2=1x+1
then put it in y=mx+b form and get
y=x+3
The ratio of 7200 to 6400 equals 1.125 in decimal form. I hope this helps!:)
