Answer:
Its A and B i beleive.
Step-by-step explanation:
Y= x + 3
1. Find the gradient(slope)
1 - 7 / - 2 - 4
=1
2. Find the y. Intercept ( c )
Y = x + c
Replace by any of the two coordinates given (4 , 7 )
7 = 4 + c
C= 3
Equation => Y = x + 3
If 4.5 was the diameter then it would be
4.5 times 3.14 = 14.13
Answer:
-4
Step-by-step explanation:
(-6)(2)-4(-1)(2)
(-12)-(-8)
