Front

What does a positive y-intercept and a negative slope indicate about a line?

Back

The line crosses the y-axis above the origin and descends as it moves to the right.

Front

Are the lines y = 3x + 5 and y = 3x - 2 parallel?

Back

Yes, they have the same slope of 3.

How do you find the x-intercept of a linear equation?

Back

Set y to 0 and solve for x.

Front

What is the general form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

What is the difference between growth and decay in exponential functions?

Back

Growth occurs when b > 1, and decay occurs when 0 < b < 1.
