Question

find the x- and y-intercepts of the graph of x + y = 18. state each answer as an integer or an improper fraction in simplest form.
answer attempt 1 out of 2
x-intercept:
y-intercept:

Explanation:

Step 1: Find the x - intercept

To find the x - intercept, we set \( y = 0 \) in the equation \( x + y=18 \).
Substituting \( y = 0 \) into the equation, we get \( x+0 = 18 \), which simplifies to \( x = 18 \). So the x - intercept is \( 18 \).

Step 2: Find the y - intercept

To find the y - intercept, we set \( x = 0 \) in the equation \( x + y = 18 \).
Substituting \( x=0 \) into the equation, we get \( 0 + y=18 \), which simplifies to \( y = 18 \). So the y - intercept is \( 18 \).

Answer:

x - intercept: \( 18 \), y - intercept: \( 18 \)
