Question

Graph the following {(x,y): x + y = 5}

Answer 1

For this case we have the following function:

`y = 5-x`

We look for the points of intersection with the x axis, doing y = 0

`0 = 5-x\\x = 5`

We look for the points of intersection with the y axis, doing x = 0

`y = 5-0\\y = 5`

We can also observe that the slope is -1.

`y = mx + b\\y = -x + 5`
