Question

Which is an equation of the line through (-1, -4) and parallel to the line 3x + 7 = 5

Answer 1

Your original equation has no y-variable. It results in x = -2/3 when you solve for x which is a vertical line. Thus, if you want a line parallel to this that goes through point (- 1, - 4), you just set x equal to the x-value in that ordered pair.

Your parallel line is x = - 1.
