x = 2

Front

What is the slope of the line represented by the equation y = mx + b?

Back

The slope is m.

Front

Define slope-intercept form of a linear equation.

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean if a system of equations has no solution?

Back

It means the lines represented by the equations are parallel and never intersect.

Front

How do you find the x-intercepts of a quadratic equation?

Back

Set y = 0 and solve for x.

Front

What is the standard form of a quadratic equation?

Back

The standard form is y = ax^2 + bx + c.
