Slope Intercept Form and Graphs

Front

What is 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.

What does the slope (m) represent in a linear equation?

Back

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

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

Back

The y-intercept (b) is the point where the line crosses the y-axis, indicating the value of y when x = 0.

Front

How do you identify the slope from the equation y = 4x + 3?

Back

The slope is 4, which means for every 1 unit increase in x, y increases by 4 units.

How do you identify the y-intercept from the equation y = -2x + 5?

Back

The y-intercept is 5, meaning the line crosses the y-axis at the point (0, 5).

Front

What is the slope of the line represented by the equation y = -3x - 5?

Back

The slope is -3, indicating the line falls as it moves from left to right.

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

Back

A slope of 0 indicates a horizontal line, meaning y remains constant regardless of x.

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates a vertical line, meaning x remains constant regardless of y.
