Equations: Identify Slope and Y-Intercept

Front

What is the definition of slope in a linear equation?

Back

The slope is a measure of the steepness of a line, represented as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

How is the slope represented in the slope-intercept form of a linear equation?

Back

In the slope-intercept form, the slope is represented by the coefficient of x in the equation y = mx + b, where m is the slope.

Front

What is the definition of the y-intercept in a linear equation?

Back

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

Front

How can you identify the y-intercept from the equation y = mx + b?

Back

The y-intercept can be identified as the constant term b in the equation y = mx + b.
