Front

For the function f(x) = -3(x-1), find f(0).

Back

f(0) = -3(0-1) = 3.

Front

Solve the system: x - y = -2 and y = -2.

Back

The solution is (-4, -2).

Front

Solve the equations: y = 8x + 1 and y = 6x + 3.

Back

The solution is (1, 9).

Front

What is the slope of the line 8x - 24y = 32?

Back

The slope m = 1/3.

Front

What is the range of the function y = 8x + 1?

Back

The range is y ≥ 0.

Front

Define a function.

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the slope-intercept form of a line?

Back

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

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope m = (y2 - y1) / (x2 - x1).

Front

What does it mean for a function to be linear?

Back

A linear function has a constant rate of change and can be graphed as a straight line.

Front

What is the y-intercept of the function y = 2x + 3?

Back

The y-intercept is 3.
