Graphing Slope-Intercept Form

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.

Front

What does the variable 'm' represent in the equation y = mx + b?

Back

The variable 'm' represents the slope of the line.

Front

What does the variable 'b' represent in the equation y = mx + b?

Back

The variable 'b' represents the y-intercept of the line.

Front

How do you find the y-intercept from the equation y = -4x - 5?

Back

The y-intercept is -5, which is the value of b in the equation.

Front

What is the slope of the line represented by the equation y = -2/3 x - 2?

Back

The slope of the line is -2/3.

Front

How do you graph a line using the slope-intercept form?

Back

Start by plotting the y-intercept (b) on the y-axis, then use the slope (m) to find another point.

Front

What is the first step in graphing a line in slope-intercept form?

Back

The first step is to plot the y-intercept (b) on the graph.

Front

If the slope is positive, what direction does the line go?

Back

If the slope is positive, the line rises from left to right.

Front

If the slope is negative, what direction does the line go?

Back

If the slope is negative, the line falls from left to right.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.
