The slope is 2 and the y intercept is 3 m = 3 and b = 2x
2(4 - 2r) = -2(r + 5)
First, divide both sides by -2. / Your problem should look like:
Second, regroup your terms. / Your problem should look like:
Third, add 4 to both sides. / Your problem should look like:
Fourth, add r + 5 + 4 to get r + 9. / Your problem should look like:
Fifth, subtract r from both sides. / Your problem should look like:
Sixth, subtract 2r - r to get r. / Your problem should look like:
![r = 9](https://tex.z-dn.net/?f=r%20%3D%209)
Answer:
r = 9

Step-by-step explanation:
honestly, I don't know
![25:405=\frac{25}{405}=\frac{5\cdot5}{81\cdot5}=\frac{5}{81}](https://tex.z-dn.net/?f=25%3A405%3D%5Cfrac%7B25%7D%7B405%7D%3D%5Cfrac%7B5%5Ccdot5%7D%7B81%5Ccdot5%7D%3D%5Cfrac%7B5%7D%7B81%7D)
OR:

1 4 0 We've got the same difference before. That means numbers will be repeated.
So:
25:405 = 0.0 6 1 7 2 5 9 2 (3 4 5 6 7 9 0 1 2)
