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.
