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

Back

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

Front

What does rounding to the nearest hundredth mean?

Back

It means to round the number to two decimal places.

Front

What is the y-intercept in the equation y = 3x + 2?

Back

The y-intercept is 2.

Front

How do you isolate x in the equation 22 + x = 36?

Back

Subtract 22 from both sides to get x = 14.
