Front

What is slope-intercept form?

Back

Slope-intercept form is a way of writing the equation of a line in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

Identify the y-intercept in the equation y = 5x - 4.

Back

The y-intercept is -4.

Front

Convert the equation y + 1 = 2(x - 2) into slope-intercept form.

Back

y = 2x - 5.

Front

What is the slope of the line represented by the equation y = -2x + 4?

Back

The slope is -2.

Front

Write the equation of a line with a slope of -4 that passes through the point (1, -1).

Back

y = -4x + 3.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

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

Back

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

Front

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

Back

The y-intercept is 2.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By + C = 0, where A, B, and C are constants.
