Front

How do you calculate the rate of change?

Back

Rate of change = (Change in altitude) / (Change in time)

Front

What are the x and y intercepts of the equation 4x - 10y = 20?

Back

x intercept = 5, y intercept = -2

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

How do you convert an equation to slope-intercept form?

Back

Isolate y on one side of the equation.

Front

What does an undefined slope indicate?

Back

A vertical line.

Front

What does a slope of 1 indicate about a line?

Back

The line rises one unit up for every one unit it moves to the right.

Front

What is the rate of change if a climber goes from 400 feet to 700 feet in 4 hours?

Back

75 ft/hour

Front

What is the significance of the y-intercept in a linear equation?

Back

It is the point where the line crosses the y-axis.

Front

What does a negative slope indicate about a line?

Back
