Question

Find the x- and y-intercepts of the graph of x + 4y = 20. State each answer as an I refer or an improper fraction in simplest form.

Answer 1

x-intercept: 20

y-intercept: 5

To find the x- and y-intercepts of the graph of the equation x + 4y = 20, we need to solve the equation for x and y, respectively.

First, to find the x-intercept, we need to set y equal to 0 and solve for x. This gives us the following equation:

x + 4(0) = 20

x = 20

Therefore, the x-intercept is (20, 0).

Next, to find the y-intercept, we need to set x equal to 0 and solve for y. This gives us the following equation:

0 + 4y = 20

4y = 20

y = 5

Therefore, the y-intercept is (0, 5).
