Explain whether every line have both an x − intercept and a y- intercept .

Answer to Problem 113E
No, every line haven’t both x − intercept and a y − intercept.
Explanation of Solution
Given:
It is given in the question that a line have both an x − intercept and a y- intercept .
Concept Used:
In this, use the common sense to understand the question and also have some basic concept of chapter.
Calculation:
A continuous line (as opposed to a line segment) must have either an x − intercept, a y − intercept , or both. Eventually, the line will cross one or the other because it travels infinitely in both directions. A horizontal or vertical line, however, will only have an x or yintercept ,not both .This is because these lines run parallel to one of the axes . For example,
Conclusion:
No, every line hasn’t both x − intercept and a y − intercept.
