Concept explainers
Find the X and y intercepts from the graph.
Answer to Problem 19PPS
The y − Intercept is 4 and the x − Intercept is 3.
Explanation of Solution
Given:
The equation:
Find the x – and y – intercepts of the graph of the linear equation. |
Concept Used:
The x -intercepts are where the graph crosses the x -axis, and the y -intercepts are where the graph crosses the y -axis.
Then, algebraically,
- an x -intercept is a point on the graph where y is zero, and
- a y -intercept is a point on the graph where x is zero.
More specifically,
- an x -intercept is a point in the equation where the y -value is zero, and
- a y -intercept is a point in the equation where the x -value is zero.
Calculation:
The equation:
To find the x − intercept, plug in y = 0 and solve for x.
To find the x − intercept, plug in x = 0 and solve for y.
The y − Intercept is 4 and the x − Intercept is 3.
Thus, the y − Intercept is 4 and the x − Intercept is 3.
