Question

If the ,midponit of sr is 6,-10, and s is 0,8 , what is the point of r?

Answer 1

the mid point is the average of the x values and average of the y values

so 6 = (0+ x)/2 and -10 = (8 + y)/2

so just solve x and y to find the coordinates of r

Answer 2

\[\text{ midpoint } =(\frac{x_1+x_2}{2},\frac{y_1,y_2}{2}) \text{ where } \\ (x_1,y_1) \text{ and } (x_2,y_2) \text{ are endpoints }\]
So you are given midpoint=(6,-10)
and one endpoint=(0,8)
So you have two equations to solve:
\[\frac{0+x}{2}=6 \\ \frac{8+y}{2}=-10\]

Answer 3

@campbell_st wins! :)

Answer 4

lol... I hate formulae like these easier to remember average of x and y

Answer 5

yes I have told people average of a and b
and they don't know what that means
