Non real complex...........
Recall that to calculate the distance between two points (a,b) and (c,d) we use the formula
![\sqrt[]{(c-a)^2+(d-b)^2}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%28c-a%29%5E2%2B%28d-b%29%5E2%7D)
In our case we have a=-2, b=5, c=4 and d=5. So we get
![\sqrt[]{(4-(-2))^2+(5-5)^2}=\sqrt[]{6^2}=6](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%284-%28-2%29%29%5E2%2B%285-5%29%5E2%7D%3D%5Csqrt%5B%5D%7B6%5E2%7D%3D6)
So the distance between both points is 6
Six hundred and two thousand one hundred and seven
(0,0),(1,3)
slope = (3 - 0) / (1 - 0) = 3/1 = 3
y = mx + b
slope(m) = 3
y int (b).....this is when x = 0...u have point (0,0)...this means ur y int is 0
now sub
y = 3x + 0 which can be written as y = 3x <===
