Math Problem Statement
Instructions: Write the equation of the line graphed below in Point-Slope form. Use the point labeled on the graph. State the slope and point.
Equation:
Slope:
Point:
Solution
From the graph provided, we can determine the slope and point based on the labeled point and the line.
Point:
The labeled point on the graph is .
Slope (m):
The slope is determined by the change in over the change in (rise over run).
- From the graph, if we move from the point to the next convenient point on the line, say :
- Rise (change in ) =
- Run (change in ) =
So, the slope .
Equation in Point-Slope Form:
The point-slope form of a line is given by:
Using the point and the slope , we substitute into the equation:
Summary:

- How do we convert this equation into slope-intercept form?
- What is the y-intercept of this line?
- Can we write the equation in standard form?
- How do we find the x-intercept of this line?
- What happens to the slope if the line becomes vertical?
Tip: When working with slopes, remember that a positive slope means the line rises from left to right, while a negative slope means it falls from left to right.
