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

How do you identify the slope from the equation y = -2x + 4?

Back

The slope (m) is -2.

Front

What does the y-intercept represent in the equation y = 12x + 10?

Back

The y-intercept (b) is 10, which is the point where the line crosses the y-axis.

Front

What is the domain of a linear function?

Back

The domain of a linear function is all real numbers unless specified otherwise.

Front

How do you find the y-intercept from the equation y = -3/2x + 4?

Back

The y-intercept is the value of y when x = 0, which is 4.

Front

What is the equation of a line with a slope of 0?

Back

The equation is y = b, where b is the y-intercept.

Front

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

Back

Start at the y-intercept (0, -3) and use the slope (rise/run) to find another point.

Front

What does it mean if a line has a negative slope?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the range of a linear function?

Back

The range of a linear function is all real numbers unless specified otherwise.

Front

How do you convert the equation y = 12x + 10 to standard form?

Back

To convert to standard form, rearrange to Ax + By = C, resulting in -12x + y = 10.
