It's called "solve the equation for 'y' ". That means move things
around so that you end up with 'y' all alone on one side, and

Divide each side by -7 : y = 9/7 x + 1

Answer:
0.69
Step-by-step explanation:
A: obese
B: diabetes
P(A) = 61
P(B) = 31
P(A and B) = 23
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 61 + 31 - 23 = 69%=0.69
