Can you help me with question for? If you can answer question 3 without the multiple choice that would be nice to. Thank you

3.) 3.5 hours

Step-by-step explanation:

3.)

5 = -2x + 12

-12 -12

-7 = -2x

\ -2 \ -2

-7/-2 = 3.5 hours

4.) The equation is written in slope intercept form which means y = mx + b

m= slope

b = y-intercept

To figure out the y-intercept, you look when the graph is 0 at x which was 32

To figure out the slope you do rise over run subtracting the two points from each other

86-32/30-0 = 54/30 = 9/5

This means the equation is y= 9/5x + 32
