Determine which two equations represent parallel lines.
(a) y = 6x – 10 (b) y = –6x + 10 (c) y = 6x + 5 (d) y = - 1/6x – 10

a and c because they both have the same slope (the slope is connected to x)

When the slope (or the number in front of x) is the same in both equations, they are parallel. Therefore, a (y=6x-10) and c (y=6x+5) are parallel because the slope is 6.

In the formula for a line, y=mx+b, m represents the slope. For two lines to be parallel, they would have to have the same slope. In the provided equations, there are only two that have the same m (slope) values, (a) and (c) both have a slope of 6.

In the equation y=mx+b, m is the slope and b is the y-intercept. If you want two parallel lines you want the slopes to be the same so that the lines will be at the same angle. They don't have to be on the same area and have the same y-intercept, but they have to have the same slope and angle so the answer will be a and c because they both have a slope of 4 (m=4).

the two equations that represent parallel lines with have the same slope. (the x term of the equation)
so its a & c

Since (a) and (c) have the same slope but different y-intercepts, they represent parallel lines.

parallel is when the slope is equal
(a) and (c)
