Front

How do you solve the equation -3(4r - 8) = -36?

Back

First, distribute -3: -12r + 24 = -36. Then, subtract 24 from both sides: -12r = -60. Finally, divide by -12: r = 5.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as f(x), where x is the input.

What does it mean for a function to be linear?

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function. A positive slope means the function is increasing, while a negative slope means it is decreasing.

Front

How can you find the slope and y-intercept from a table of values?

Back

To find the slope, calculate the change in y divided by the change in x between two points. The y-intercept is the value of y when x = 0.
