By looking at linear equations we can tell how they will interact in the coordinate plane. Which of the following are possible if two linear equations are graphed? Select all that apply. -They could be parallel to each other. -They could intersect at two points. -They could be perpendicular to each other. -They could be skew lines. -They could be the same line.

-They could be parallel to each other. -They could be perpendicular to each other. -They could use the same line.

The lines of the equations are parallel, perpendicular, or neither. y = -x + 3 y = -x - 3 -parallel -perpendicular -neither

Parallel

The lines of the equations are parallel, perpendicular, or neither. y = 2x + 3 y = 2x -parallel -perpendicular -neither
