Answer (this one's written in slope-intercept form):
Step-by-step explanation:
1) Lines that are parallel to each other have the same slope. The line is in slope intercept form, or form, and the number in place of represents the slope. Knowing this, it looks like is in the place of the in that equation, so is the slope - and the slope we need to use for the answer, too.
2) Once you know a point that the line must pass through and a slope, you can write an equation with point-slope form, or . is the slope and and are the x and y values of the point it must pass through. So, substitute for , 0 for , and -3 for . Simplify and isolate y to put it in slope-intercept form:
3) Thus, is the answer. It's written in slope-intercept form.

Answer:
D) x = 14
Step-by-step explanation:
x/2 = 7
We want to isolate x
We can multiply by 2 on each side.
2 * x/2 = 7*2
x = 14
