Front

What does the inequality 6 > x mean?

Back

x is any number less than 6.

Front

What is the y-intercept of the equation 2x - 5y = 35?

Back

(0, -7)

Front

How do you find the slope of the equation 2y + 4x = 8?

Back

Rearrange to slope-intercept form (y = mx + b) to find the slope m = -2.

Front

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

Back

-5

Front

Is the equation y = x^2 + 3 linear or nonlinear?

Back

Nonlinear

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

The slope is 3/2.

Front

What does it mean for an equation to be linear?

Back

It can be graphed as a straight line and has the form y = mx + b.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

How do you determine if a point (x, y) lies on the line represented by the equation y = 2x + 1?

Back

Substitute x into the equation and see if the resulting y matches.

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.
