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

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

Back

The slope is the coefficient of x, which is 4.

Front

What does the y-intercept represent in the equation y = mx + b?

Back

The y-intercept (b) is the point where the line crosses the y-axis.

Front

If the slope of a line is 1/2, what does this indicate about the line's steepness?

Back

A slope of 1/2 indicates that for every 2 units you move horizontally, the line rises 1 unit.

Front

What is the y-intercept of the equation y = -4x - 5?

Back

The y-intercept is -5.

Front

How can you graph the equation y = 1/3x - 2?

Back

Start at the y-intercept (-2) on the y-axis, then use the slope (1/3) to find another point.

Front

What is the equation of a line with a slope of -2/3 and a y-intercept of -2?

Back

The equation is y = -2/3x - 2.

Front

How do you convert the equation y = 2x + 1 to slope-intercept form?

Back

It is already in slope-intercept form: y = mx + b.

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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