Step-by-step explanation:
The problem is basically asking for the roots, or the x-intercepts. To do this, follow the quadratic formula:
b is the second coefficient(+13)
a is the first coefficient(5)
c is the third coefficient(-6)
When the formula is negative, it just means to flip the sign from a positive to negative or negative to positive. Plug in and simplify.

How to get that answer:
The slope is the rate of change for any linear function.
Apply the slope formula for any two points on the diagonal line.
I'll use the points (-4, -3) and (0, 4)
The slope is m = 7/4
This indicates that each time we go up 7 (rise), we also go to the right 4 units (run)
slope = rise/run = 7/4
rise = 7, run = 4
The fraction 7/4 converts to the decimal form 1.75
