, or rise over run.
The change in
x
x
is equal to the difference in x-coordinates (also called run), and the change in
y
y
is equal to the difference in y-coordinates (also called rise).
Substitute in the values of
x

and
y
y
into the equation to find the slope.

Answer:
It is located in the 3rd quadrant since x = -3 and y = -4.
Tan42°=x/35
x=35tan42° units
x≈31.51 units (to nearest hundredth of a unit)
