Finding Slope and Function Test

Front

What is the definition of slope?

Back

Slope is a measure of the steepness or incline of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

Front

What type of slope is represented by a line that goes up from left to right?

Back

Positive slope.

Front

What type of slope is represented by a line that goes down from left to right?

Back

Negative slope.

Front

What does a slope of zero indicate about a line?

Back

A slope of zero indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

How can you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph of the relation at more than one point, it is not a function.

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

Convert the equation y - 3 = 2(x - 1) to slope-intercept form.

Back

y = 2x + 1.

Front

What is the y-intercept in the equation y = 3x + 5?

Back

The y-intercept is 5.
