They are parallel because
lines AB and CD are vertical
lines.
78°
75°
They are not parallel because
the two given angles are not
supplementary.
They are not parallel because
the two given alternate
interior angles are not
congruent.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.

Angle 1 and angle 2 are a linear pair . m angle 1 =x-39 and m angle 2 =x+61 find the measure of each angle
