What is a negative slope?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, resulting in a line that descends from left to right.

What is a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically in the form f(x) = ax² + bx + c, where a, b, and c are constants.

Front

What does it mean for a line to be a factor of a quadratic graph?

Back

A line is a factor of a quadratic graph if it intersects the graph at its x-intercepts, indicating the roots of the quadratic equation.

Front

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.

Front

What is the 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 for a graph to have an x-intercept of -4 and a y-intercept of 2?

Back

It means the line crosses the x-axis at (-4, 0) and the y-axis at (0, 2).

Front

What is the difference between a linear function and a quadratic function?

Back

A linear function has a constant rate of change (straight line), while a quadratic function has a variable rate of change (parabola).
