Can someone please help me

[Need Help!!!]

Im having a tuff time this geometry stuff. Im taking it in 8th grade and dont know if im ready for it. but oh well already half way through the year. I dont understand the coordinate stuff. here is my ques:

what is the mid point of WZ and the slope of WZ.

W= 0,b
Z=a,0

Finding the midpoint is very easy
Can you find an average? The average of a and b is \(\displaystyle \frac{{a + b}}{2}\).

To find the midpoint just average the coordinates.
Given two points \(\displaystyle \L
\left( {p,q} \right)\;\& \;(r,s)\) the midpoint is \(\displaystyle \left( {\frac{{p + r}}{2},\frac{{q + s}}{2}} \right)\).

The slope determined by those points is \(\displaystyle \L
m = \frac{{s - q}}{{r - p}}\).
