Answer: y= 3x - 
Step-by-step explanation:
Since we know the slope and a set of coordinates we can insert them into the formula y=mx+b and find what b is.
y=mx+b
-1/2=3(2)+b
-1/2=6+b
-1/2-6=6-6+b
-6 1/2=b
Therefore the equation is y=3x - 
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.
First, change it into general form(y=my+b).
3y=6x-1+10
3y=6x+9
y=2x+3
So, the slope is 2, and the y-intercept is 3
