are these 2 equations parallel?
y=2x+5
-2x+y=-2
thanks, and no answers such as "x" and nothing else like on person has been doing

yes
cuz
y=mx+b
mx= the slope of the line
so..
y= 2x+5
slope = 2
-2x+y = -2
move the 2 over to the other side
y=2x-2
slope = 2
YES they are PARALLEL
FYI - parallel slopes is when 2 lines have the same slope EX: this problem
-perpendicular lines is when 2 lines have the opposite slope EX: Line one has a slope of 5, in order to be perpendicular line 2 slope would have to be -1/5 (negative)

Parallel equations have the same slope. So, what I would do, I would solve the second equation for y first:
-2x+y=-2
y=-2+2x
So, the slope of this equation is 2, which is the same as the first one, meaning that, yes, the two equations are parallel.

yes, because when u move the -2x to the right side, it becomes 2x which is exactly the same as the other slope. When two slopes are the same the lines are parallel.

Rewrite the second equation in slope-intercept form
y=2x-2, y=2x+5
yes, they are parallel because they both have slopes of 2

leave y=2x + 5 alone
for other eq... you..
add 2x to each side so its y= 2x -2
parallel lines = same slope
slope of line 1 = 2x
slope of line 2 = 2x
parallel yes
