A16 (GEN) - 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 identify the slope from the equation y = 4x + 3?

Back

The slope is 4.

Front

If a line has a slope of -2, what does this indicate about its direction?

Back

The line decreases; for every 2 units up, it goes 1 unit to the right.

Front

What is the y-intercept of the line represented by the equation y = -1/2x + 5?

Back

The y-intercept is 5.

Front

How do you graph the equation y = 3x + 1?

Back

Start at (0,1) on the y-axis, then use the slope of 3 to rise 3 units and run 1 unit to the right.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

If a line passes through the points (2, 3) and (4, 7), what is the slope?

Back

The slope is 2.
