linear functions

Front

Identify the slope and y-intercept of the linear function: y = 3 - x

Back

Slope: -1, Y-intercept: 3

Front

What is the definition of a function?

Back

A function is a relation where every input has only ONE output.

Front

Write a rule for the following scenario: Miles has joined a weight loss program. His weight is 225 lbs and he is losing weight at a rate of 3 lbs per week.

Back

y = 225 - 3x

Front

What slope is parallel to m = 3/4?

Back

The slope parallel to m = 3/4 is 3/4.

Front

Which of the following has a y-intercept of 3? y = 3x + 2, x = 3, y = 2x + 3, y = x

Back

y = 2x + 3

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 between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.

Front

What is the y-intercept of the line represented by the equation y = 5x - 7?

Back

The y-intercept is -7.
