Back

The y-intercept represents the initial deposit in the account.

Front

Given the equation 6x – 3y = 12, what is the y-intercept?

Back

The y-intercept is -4.

Front

If f(x) = 9 – 3x and g(x) = 5x – 7, what is f(x) + g(x)?

Back

f(x) + g(x) = 2x + 2.

Front

Back

2, 4, 8, 16 is not an arithmetic sequence.

Front

Evaluate f(2) for f(x) = 3x + 1.

Back

f(2) = 7.

Front

What is an arithmetic sequence?

Back

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant.

Front

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

Back

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

Front

What is the formula for 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 if a function is linear?

Back

A function is linear if it can be graphically represented as a straight line.

Front

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

Back

The y-intercept is 3.
