Front

What is the slope of a line that passes through the points (2, 4) and (6, 12)?

Back

The slope is 2.

Front

What is the domain and range of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

Domain: {0, 1, 2, -4}, Range: {1, -3, -4}

Front

Convert the equation 5x - 5y = 25 to slope-intercept form.

Back

y = x - 5

Front

How does the equation y = x + 2 shift from the parent function?

Back

It is translated up 2.

Front

For the equation y - 3 = 2(x + 4), what is the slope and what point does the line contain?

Back

Slope: 2, Point: (-4, 3)

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of the y-value with respect to the x-value.

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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