Extra Credit: 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 of a linear equation?

Back

To find the y-intercept, set x = 0 and solve for y.

Front

What is the slope of the line represented by the equation y = -3x + 4?

Back

The slope is -3.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

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 the equation y = -x + 2?

Back

The first step is to plot the y-intercept, which is 2.

Front

After plotting the y-intercept, what is the next step in graphing?

Back

Use the slope to determine the next point by rising or falling and running left or right.
