Parallel ,perpendicular, neither y=4x+5 and -4x +y=-13

here,

slope of line y=4x+5(m1)=-a/b

=4

slope of line -4x+y=-13(m2)=-a/b

4

here m1=m2 so,these are parallel to each other.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

answer: i guess 105 degrees?
