Front

What does the letter 'm' represent in the slope-intercept form of a linear equation?

Back

The letter 'm' represents the slope of the line.

Front

What is the definition of range in a function?

Back

The range is all the possible outputs (y values) of a function.

Front

How do you evaluate the function f(x) = 6x + 2 at x = -2?

Back

To evaluate, substitute -2 for x: f(-2) = 6(-2) + 2 = -12 + 2 = -10.

Front

What does it mean if a line has an undefined slope?

Back

An undefined slope indicates a vertical line, where the x-value does not change.

Front

What is the definition of domain in a function?

Back

The domain is all the possible inputs (x values) of a function.

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

How can you determine the slope from two points (x1, y1) and (x2, y2)?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept in the equation y = 3x + 4?

Back

The y-intercept is 4, which is the value of y when x = 0.

Front

What does it mean for a function to be linear?

Back

A linear function is one that graphs to a straight line, having a constant rate of change.

Front

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

Back

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