Question 1000947: What equation is parallel to y=2x+1?
Answer by Cromlix(4381)   (Show Source):
You can put this solution on YOUR website! Hi there,
If lines are parallel to one another
they have the same gradient.
i.e m1 = m2
y = 2x + 1 has a gradient of 2
so any line equation with a gradient
of 2 will be parallel to it.
eg.
y = 2x + 7
y = 2x -5
y = 2x + 21
The only difference will be the
intersection with the 'y' axis.
in y = 2x + 1 intersection is (0,2)
Hope this helps :-)
