Answer:
The slope is 
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
In this problem we have

so
Convert to slope intercept form
Isolate the variable y



The slope is 
The square roots of 64 is A B and C.
