How do you graph the equation y = mx + b?

Back

Plot the y-intercept (b) on the y-axis, then use the slope (m) to find another point.

Front

What is the slope of the line represented by the equation y = 1/2x + 2?

Back

The slope is 1/2.

Front

What does it mean if two lines are parallel when graphing a system of equations?

Back

It means there is no solution, as the lines never intersect.

Front

What is the significance of the point (2, 3) in the context of a system of equations?

Back

It is the solution to the system, meaning both equations are satisfied at this point.
