Which is not an equation of the line that passes through the points (1, 1) and (5, 5)?

y - x = 0
x - y = 0
-x - y = 0

Step-by-step explanation:

The equation of line passing through two points (a,b) and (c,d) is given by :-

Then , the equation of line passing through two points (1, 1) and (5, 5) is given by :-

It can be written as

Hence, the is not an equation of the line that passes through the points (1, 1) and (5, 5).

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
