Algebra Foundations REVIEW Test Part 1

Front

What is the slope of a line in the equation 4x + 3y = 9 + 4x?

Back

The slope is 0.

Front

What is the slope of a line that passes through the points (-12,3) and (-12,20)?

Back

The slope is undefined.

Front

Back

x = 12.

Front

What is a function?

Back

A relation where each input has exactly one output.

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.

Front

What does it mean if a line has a slope of 0?

Back

The line is horizontal.

Front

What does it mean if a line has an undefined slope?

Back

The line is vertical.

Front

What is the y-intercept of the line represented by the equation y = 2x + 3?

Back

The y-intercept is 3.

Front

How do you determine if a graph represents a function?

Back

Use the vertical line test: if a vertical line intersects the graph more than once, it is not a function.

Front

Back

The region below or on the line y = 2x + 3.
