How do you find the x and y intercepts for #x + y = 1#?

Answer 1

Savannah Anderson

#y=1,x=1#

Here is a graph of the equation: graph{1-x [-10, 10, -5, 5]}

We can see the y-intercept is given where #x=0# and the x-intercept is given where #y=0#,

So if we set #y=0# we get: #x+0=1 -> x=1#

And similarly, #x=0# #0+y=1 -> y=1#

Thus we have our intercepts at:

#y=1,x=1#

To find the x-intercept, let y = 0 and solve for x. To find the y-intercept, let x = 0 and solve for y. For the equation x + y = 1:

x-intercept: (1, 0) y-intercept: (0, 1)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
