The information is really hard to follow, you should ask the question with a screenshot of the data table.
The last one Does not have an awnser there is no like terms
Perpendicular means that you will flip and change sign in this case we have -3 when we flip it and change sign we will get 1/3
So,
First we have to find b:
2=1/3(3)+b
2=1+b
1=b
Second you just write your equation:
Y= 1/3x + 1
Hope it help sweetheart!!
What is the vertex form of the equation y=-x^2+8x-3
4(6)-6(3)+(8)
24-18+8
6+8
14
