Answer
Another point with a negative
-value is
, where
is the y-coordinate of the vertical intercept.
Solution
To solve this problem, we’ll use the information provided about the slope and the vertical intercept.
Given:
- Slope:
(which is equivalent to ) - Vertical Intercept: Let’s assume it’s at
(where is the y-coordinate of the intercept).
Steps to Find Another Point with Negative
-Value:
-
Understand the Slope:
- The slope
indicates that for every 3 units you move horizontally to the left (since the run is negative), the vertical position increases by 2 units.
- The slope
-
Starting at the Vertical Intercept:
- Start at
.
- Start at
-
Apply the Slope to Find the Next Point:
- Horizontal Movement (
): Move -3 units (to the left). - Vertical Movement (
): Move +2 units (upwards).
- Horizontal Movement (
-
Calculate the Coordinates of the Next Point:
- New
-coordinate: - New
-coordinate:
- New
-
Resulting Point:
-
Example with a Specific Vertical Intercept:
If, for instance, the vertical intercept is
, then:
- The next point would be
.
Final Answer:
Assuming the vertical intercept is
(as an example), another point with a negative
-value is:
However, without the specific value of the vertical intercept from Example 2, the general form of the answer is:
Where
is the y-coordinate of the vertical intercept.

Bonus Knowledge
Starting at the vertical intercept, which is typically the point
where
is the y-intercept, you can use the slope of
to find the next point. The slope tells us that for every 2 units you move up (in the y-direction), you’ll move 3 units left (in the x-direction).
From the vertical intercept
, moving up 2 units takes you to
. From there, moving left 3 units results in the point
. So, a point on the graph with a negative x-value is
.
Choose a specific y-intercept value (for example, if
): then the point would be
.
