What is the slope of the line represented by the equation y - 3 = 2(x + 4)?

Back

The slope of the line is 2.

Front

What point does the line y - 3 = 2(x + 4) contain?

Back

The line contains the point (-4, 3).

Front

How do you find the x-intercept of the equation 5x - 3y = 15?

Back

Set y = 0 and solve for x. The x-intercept is (3, 0).

Front

How do you find the y-intercept of the equation 5x - 3y = 15?

Back

Set x = 0 and solve for y. The y-intercept is (0, -5).

Front

Convert the equation y - 2 = 9(x + 1) into slope-intercept form.

Back

The slope-intercept form is y = 9x + 11.

Front

What is the general form of a linear equation?

Back

The general form is Ax + By + C = 0.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

The slope m = (y2 - y1) / (x2 - x1).

Front

What is the significance of the y-intercept in a linear equation?

Back

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

Front

How do you graph the equation 2x + 4y = 12?

Back

Rearrange to slope-intercept form and plot the y-intercept and slope.
