What is the equation of a linear function?

Back

A linear function can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

Convert the standard form equation 4x - 3y = 15 into slope-intercept form.

Back

y = (4/3)x - 5

Front

What does a correlation coefficient of r=0.3 indicate?

Back

It indicates a weak positive correlation between the two variables.

Front

What is the equation of a line with a zero slope that goes through the point (6, 7)?

Back

y = 7

Front

What is the range of the graph if 1 ≤ y ≤ 5?

Back

The range is the set of all possible y-values, which is [1, 5].

Front

What is the slope of the line represented by the equation y = 3x + 16?

Back

The slope is 3.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 in the equation and solve for y.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

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

Back

It means that as x increases, y decreases.

Front

How can you determine if a function is linear?

Back

A function is linear if it can be graphed as a straight line.
