Question

Which of the following is an equation of a line that is parallel to the line y=-2x+7 in the standard (x,y) coordinate plane

Answer 1

To do this problem we are going to need to know the coordinates (x,y) of a point that the line passes through. Because the lines are parallel, the two lines will have identical slopes. In an equation in y=mx+b form, m is the slope.
