Question

HELP! Distance and Midpoint Formulas:
could someone help me with this? I know its not hard, but I'm really bad at maths:

Answer 1

@jorgesnz did you attempt the formula I gave you for qn 2 to 5?

Answer 2

the midpoint is the average of x's and y's

e.g. points (1, 5) and (6, 11) the the midpoint is x = (1 + 6)/2 y = (5 + 11)/2

x = 3.5 y = 8

Midpoint (3.5, 8)

Midpoint formula

\[x_{m} = \frac{x_{2} + x_{1}}{2} ........ y_{m} = \frac{y_{2} + y_{1}}{2}\]

Distance Formula

its just pythagoras' theorem... plot the points on the number plane.... find the vertical and horizontal distance

\[d = \sqrt{(x_{2} - x_{1})^2 + (y_{2} - y_{2})^2}\]

hope it helps
