Front

Parallel Lines never intersect because...

Back

they have the same slopes.

Front

Write in slope intercept form: 5x - 3y = -9

Back

y = (5/3)x + 3

Front

If a system of equations has no solution, what does the graph look like?

Back

parallel lines

Front

How can you tell if a point is a solution to a system?

Back

The (x,y) coordinates satisfy both equations.

Front

What is a system of equations?

Back

A set of two or more equations with the same variables.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope but different y-intercepts.

Front

What is slope-intercept form?

Back

The equation of a line in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope of a line given two points?

Back

Use the formula m = (y2 - y1) / (x2 - x1).

Front

What does it mean if two lines intersect at one point?

Back

The system of equations has one unique solution.
