Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

Identify the slope in the equation y = 2x + 4.

Back

The slope (m) is 2.

Front

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

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form.

Front

Write the slope-intercept form of a line with a slope of -3 and a y-intercept of 0.

Back

The equation is y = -3x.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the slope of a line that rises 3 units for every 4 units it runs?

Back

The slope is 3/4.

Front

If a line has a slope of 4/3, what does this indicate about its steepness?

Back

A slope of 4/3 indicates that the line is relatively steep, rising 4 units for every 3 units it runs.

Front

Back

n = -5.

Front

What does a slope of $1/2 miles driven mean?

Back

It means that for every 1 mile driven, the cost increases by $0.50.

Front

What is the significance of a negative slope?

Back

A negative slope indicates that as one variable increases, the other variable decreases.
