Graphing Linear Equations

Front

What is the point where the line crosses the y-axis called?

Back

y-intercept

Front

What is the y-intercept of the line (0, -1)?

Back

(0, -1)

Front

Identify the y-intercept for the function: y = -3x.

Back

(0, 0)

Front

What is the equation of the line with a slope of -4/5 and y-intercept of 3?

Back

y = -4/5x + 3

Front

Which graph represents the equation y = -x + 3?

Back

Graph A

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y over the change in x.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the value of y when x is 0, indicating where the line crosses the y-axis.

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 standard form of a linear equation?

Back

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

Front

What does it mean if a line has a positive slope?

Back

A positive slope indicates that as x increases, y also increases.
