Read each question carefully and follow the instructions. Show all your work where applicable.

Directions: Identify the slope (m) and y-intercept (b) for each linear equation.

1. y = 3x + 5 Slope (m): Y-intercept (b):

2. y = -2x - 1 Slope (m): Y-intercept (b):

3. y = (1/2)x + 4 Slope (m): Y-intercept (b):

4. y = x - 7 Slope (m): Y-intercept (b):

5. Which equation represents a line with a slope of 4 and a y-intercept of -2?

y = -4x + 2

y = 4x + 2

y = 4x - 2

y = -2x + 4

6. What is the y-intercept of the line represented by the equation y = -5x + 10?

-5

-10

Directions: Write the equation of the line in slope-intercept form (y = mx + b) given the following information.

7. Slope (m) = 2, Y-intercept (b) = 3

8. Slope (m) = -1/4, Y-intercept (b) = 0

Directions: Graph the following linear equations on the coordinate plane.

9. y = 2x + 1

10. y = -x + 3
