Let the four consecutive numbers be x,x+1,x+2,x+3.
Now the product of second and third number=(x+1)(x+2)=x²+3x+2=k
Product of first and fourth number=x(x+3)=x²+3x=k-2
A.T.Q
product of second and third number= product of first and fourth number+2
Hence proved
If your given slope is - 35, your equation starts off as y = - 35x + b
Now we plug in the point given and solve for b.
- 3 = - 35(6) + b
- 3 = - 210 + b
207 = b
So your equation is:
y = - 35x + 207
Simple multiplication..
