Math Problem Statement
Find the x- and y-intercepts of the line. Enter each answer as an ordered pair. 9y - x = -1.
Solution
The equation of the line is:
To find the x-intercept and y-intercept, we proceed as follows:
1. Find the x-intercept:
The x-intercept occurs when . Substitute into the equation:
So, the x-intercept is:
