2) Solve for y.

2x = 3y – 10

3) Find the slope of the line containing the two given points.

(-4, -5) and (9, 3)

4) Write the slope-intercept equation (y = mx + b) for a line with the given characteristics.

m = 3, passing through (1, -2)

5) Provide an appropriate response.

Find the standard form of the equation of the line passing through the two points.

(2, - 6) and (- 9, 6)

6) Solve the problem.

Persons taking a 30-hour review course to prepare for a standardized exam average a score of 620 on that exam. Persons taking a 70-hour review course average a score of 792. Find a linear function S (t), which fits this data, and which expresses score as a function of time

7) Solve by the substitution method.

x + 5y = -14

-3x + 4y = -34

8) Solve the system of equations by the elimination method.

-5x + 9y = 10

2x + 7y = -4
