What does it mean for two lines to intersect on a graph?

Back

It means that the two equations have a common solution, represented by the point of intersection.

Front

How do you determine if a point is a solution to a system of equations?

Back

Substitute the point into both equations; if it satisfies both, it is a solution.

Front

What is the graphical representation of the equation y = -x + 3?

Back

A straight line with a slope of -1 and a y-intercept of 3.

Front

What does it mean if two lines are parallel?

Back

They have the same slope but different y-intercepts, meaning they never intersect.
