1. What is the equation of the line shown in the graph below?

y = 2x + 3

2. Write the equation of the line that passes through the points (2,5) and (4,9).

y = 2x + 1

3. Graph the equation y = 3x - 2.

(Graph the line with a slope of 3 passing through the y-intercept of -2)

4. Determine the slope of the line represented by the equation y = -4x + 7.

The slope is -4.

5. Identify the y-intercept of the line represented by the equation y = 0.5x + 4.

The y-intercept is 4.

6. Determine the x-intercept of the line represented by the equation y = -6x + 2.

The x-intercept is approximately 0.33.

7. Graph the equation y = -2x + 5.

(Graph the line with a slope of -2 passing through the y-intercept of 5)

8. Solve the system of equations:

y = 2x + 3
y = 3x - 1

The solution is x = -4, y = -5.
