Unit 2 8.PAR.4 Review

Front

What is the slope of the line represented by the equation 3y - 9x = -4?

Back

The slope is 3.

Front

How can you identify a nonlinear function from a table of values?

Back

A nonlinear function will not have a constant rate of change between the x and y values.

Front

What does a greater rate of change indicate in a linear function?

Back

It indicates that for each unit increase in x, y increases by a larger amount.

Front

Convert the equation y - 5 = 3(x - 2) to slope-intercept form.

Back

y = 3x - 1.

Front

What is a linear equation?

Back

A linear equation is an equation that graphs to a straight line and can be written in the form y = mx + b.

Front

What does the term 'slope' refer to in a linear equation?

Back

Slope refers to the steepness of the line, calculated as the rise over run.

Front

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

Back

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

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept in the equation y = 2x + 3?

Back

The y-intercept is 3.

Front

What does it mean if a function is linear?

Back

It means that the function can be represented by a straight line on a graph.
