What I do first (easier for me) is to change it into slope-intercept form
2x-9y=-36
-9y=-2x-36                2x
---------------   =    y= ---- +4
        -9                       9
the slope is whatever is in front of x, in this case 2/9

Answer:

Marcus will run an average of 4.3 miles after 36 minutes.

Step-by-step explanation:

Given:

Marcus runs an average mile in 8.3 minutes.

1 miles = 8.3 minutes

We need to find miles he ran at same average in 36 minutes.

How many miles = 36 minutes

Using Unitary Method we will find miles he run at 36 mins by multiplying 1 mile with 36 minutes and the dividing it with 8.3 minutes we get;

An Average mile run after 36 min = $\frac{36}{8.3}= 4.337\ miles$

Rounding to nearest tenth we get ≈ 4.3 miles.

Hence, Marcus will run an average of 4.3 miles after 36 minutes.
