Which statement describes Kayla's solutions?

• Her solutions are correct.

• She marked the y-intercepts instead of the x-intercepts.

• She marked the y-intercepts instead of the intersection point of the two lines.

• She marked only the y-intercepts instead of the x- and y-intercepts.

Decide if the following statements are true or false about the graph.

Groups:

(a) True

,

(b) False

• The slope(m) of the lines are equal

• The lines are perpendicular which means they will not ever cross.

• The lines will eventually touch, so the system has one solution

• The lines will not intersect, so the system has no solution

• The line are parallel, so the system has no solution

• The slopes are equal, so the system has infinitely many solutions
