Question

graph the equation and identify the y intercept
x+5y=15
I have already graphed it the y intercept needs to be an ordered pair
is it (0, 15)

Answer 1

To find the y-intercept, simply plug in x = 0 and solve for y


x+5y=15


0+5y=15


5y = 15


y = 15/5


y = 3


So when x = 0, y is y = 3


This gives us the y-intercept as the ordered pair (0, 3)

Answer 2

You have your thinking backwards, but I think you have the right idea
