Math Problem Statement
Solution
The equation given in the image is in slope-intercept form:
This equation follows the form , where:
- is the slope of the line (here, ),
- is the y-intercept (here, ).
Step-by-step Graphing Instructions:
-
Plot the y-intercept: The y-intercept is . So, plot a point at (0, 3) on the y-axis.
-
Use the slope: The slope is , meaning for every 3 units you move to the right along the x-axis, move 8 units down (since the slope is negative). From the point (0, 3), move:
- 3 units to the right (positive direction on the x-axis),
- 8 units down (since the slope is negative).
This leads to the point (3, -5).
-
Draw the line: Now, connect the two points (0, 3) and (3, -5) with a straight line.
The graph should show a downward sloping line passing through these points.

Here are five related questions:
- How do you find the slope from two points on a line?
- What is the significance of the y-intercept in real-life problems?
- How would you graph a line with a positive slope?
- What happens to the graph if the slope becomes zero?
- How do you convert from standard form to slope-intercept form?
Tip: When plotting lines, always remember to check the scale on both the x and y axes to ensure accuracy.
