Line ef has an equation of a line y = -2x + 7, and line gh has an equation of a line y = x -1. these two lines are
parallel because the slopes of the lines are equal
perpendicular because the slopes are opposite reciprocals
the same line when graphed
intersecting but not at a right angle

How can you solve an equation with a variable on both sides? complete the explanation. you can solve the equation by using *(blank)* operations to get the variable terms on one side of the equal sign and the constant terms on the *(blank)* side. then *(blank)* both sides by the coefficient of the resulting variable term.
