What is an x-intercept?

Back

An x-intercept is the point where a graph crosses the x-axis. At this point, the value of y is zero.

Front

Identify the x-intercept of the point (-2, 0).

Back

The x-intercept is (-2, 0) because it is where y = 0.

Front

Solve the equation: 32 - 7x = -6(x + 3). What is the value of x?

Back

x = 50.

Front

Multiply the binomials: (3x - 5)(2x + 3). What is the result?

Back

Front

How do you find the slope from a table of values?

Back

The slope (m) is calculated as the change in y divided by the change in x (m = (y2 - y1) / (x2 - x1)).

Front

What is the slope of a line if the change in y is -4 and the change in x is 1?

Back

The slope is -4.

Front

Write the equation of a line with a slope of -1/3 that passes through the y-intercept -2.

Back

Front

What does it mean for a line to have a positive slope?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.

Front

What does it mean for a line to have a negative slope?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.
