Solution:
<u>A few changes were made:</u>
- 4 as 4.00.
- 0.3 as 0.30
<u>New equation:</u>
- 4 + 0.3 + 0.09 = 4.00 + 0.30 + 0.09
<u>Solving the equation:</u>
- 4.00 + 0.30 + 0.09
- => 4.39 (Refer to image for work)
Correct option is B.
Given two points, say points A and B, we can use the slope formula to find the slop of the line:
If A has coordinates of (w,c) and B has coordinates of (y,z), we can find the slope.
![\frac{z-c[tex]y-w= \frac{z-x}{y-w} (x-c)](https://tex.z-dn.net/?f=%20%5Cfrac%7Bz-c%5Btex%5Dy-w%3D%20%5Cfrac%7Bz-x%7D%7By-w%7D%20%28x-c%29)
}{y-w} [/tex]
Now we can say that we can use the point slope form formula:
Now we can substitute m for the slope, and use any points to plug in
and 
.
Hope this helps! :^)
