Answer:
![y=2x-2](https://tex.z-dn.net/?f=y%3D2x-2)
Step-by-step explanation:
Because the coordinates for x = 0 is (0,-2) so that's your y- intercept.
Then if you all you have to do is make sure that you have the correct slope.
So i just made a table on paper and started going up and seeing what slope i'd need to match the table on the screen.
![2(0)-2=-2\\2(1)-2=0\\2(2)-2=2\\2(3)-2=4](https://tex.z-dn.net/?f=2%280%29-2%3D-2%5C%5C2%281%29-2%3D0%5C%5C2%282%29-2%3D2%5C%5C2%283%29-2%3D4)
Uhh........he was supposed to do 2,4,6,8,10???
(a−b)+a+(a+b)=45
⟹3a=45
a=15
a(a+b)=300
⟹15(15+b)=300
⟹225+15b=300
⟹15b=300−225
⟹15b15=7515
b=5
a−b=10⟹a=15⟹a+b=20
The three numbers are 10, 15, and 20.
Proof:
10+15+20=45✓
