What is the translation of the parent function f(x) = x when it is moved 2 units right and 8 units down?

Back

g(x) = (x - 2) - 8

Front

How do you convert the equation y = -\frac{2}{3}x + 4 into standard form?

Back

2x + 3y = 12

Front

What is the equation of the best-fit line using the points (3, 0.7) and (11, 2.7)?

Back

y = 0.25x - 0.05

Front

What is the equation of a line that passes through the point (8, 33) with a slope of 3?

Back

y = 3x + 9

If the depth of water in a tank is modeled by d(t) = 38 - 2t, how long until the tank is empty?

Back

19 minutes

Front

What does the slope of a line represent in a linear equation?

Back

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

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = \frac{y2 - y1}{x2 - x1}.

Front

What is a parent function in mathematics?

Back

A parent function is the simplest form of a function in a family of functions.

Front

What does it mean for a function to be translated?

Back

A translation shifts the graph of a function horizontally, vertically, or both.
