Question

need help
determine whether the graphs of the equations are parallel lines
x=2
x=4

Answer 1

yes they are parallel if you graph them.

Answer 2

the slope of the line x=2 is?
the slope of the line x=4 is

Answer 3

their parallel to each other yes.

Answer 4

ok but how do i determine what the slopes are for each

Answer 5

gradient = rise/run
therefore, the gradient for x=2 is 0/2=0
and the gradient for x=4 is 0/4 = 0
hence both lines are parallel

Answer 6

as you can see in the graph the lines are parallel to each other

Answer 7

so then the slopes would be?
