we have the points
(-3,0) and (3,5)
Remember that
the first coordinate corresponds to the x-coordinate
the second coordinate corresponds to the y-coordinate
so
(-3,0) means
x=-3 (3 units at the left of x=0)
y=0
(3,5) means
x=3 (3 units at right of x=0)
y=5 (5 units up of y=0)
see the attached figure to better understand the problem
