find the x/y intercept
Solution
The image contains two equations where you are asked to find the x and y intercepts. The equations are:
Let's go step by step for each one.
1. For the first equation:
Y-intercept:
The y-intercept occurs when .
Substitute into the equation:
So, the y-intercept is .
X-intercept:
The x-intercept occurs when .
Set and solve for :
So, the x-intercept is .
2. For the second equation:
Y-intercept:
The y-intercept occurs when .
Substitute into the equation:
So, the y-intercept is .
X-intercept:
The x-intercept occurs when .
Set and solve for :
For this fraction to be 0, the numerator must be 0:
