Answer Key

1. C. The equation for slope is y = mx + b, in which m is slope.

2. B. Slope can be found with the following equation: (y2 - y1)/(x2 - x1).

3. A. Solve for x in the first equation, then substitute this value into the second equation.

4. B. It is important to set up the equation so that it will be performed correctly according to the order of operations.

5. A. Divide 84 by 3, and then add this dividend to 84.

6. B. Multiply the number of words typed per minute by the number of minutes in an hour.

7. A. Subtract 220 from 700, then multiply the difference by 0.3. Subtract this amount from the difference to find the answer.

8. B. Solve for y by adding 3 to both sides and then dividing both sides by 4.
