Front

What are the steps for graphing a line?

Back

1. Plot y-intercept 2. Count slope ratio to plot second point 3. Draw the line.

Front

What is a system of equations?

Back

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

Front

Front

What is the y-intercept of the line represented by the equation y = 2x + 3?

Back

3

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean if a system of equations has infinitely many solutions?

Back

The equations represent the same line.
