Answer:
-19
Step-by-step explanation:
~ Distribute:
- 11 = 1 / 2 x + -3 / 2
~ Flip the equation:
1 / 2 x + -3 / 2 = -11
~ Use transposition method:
(take -3 / 2 to the other side)
1 / 2 x = -11 - (-3 / 2)
= -19 / 2
x = -12 / 2 * 2
= -19

Answer:
y = 9 + 19x
Step-by-step explanation:
To find the equation matching a set of data, you simply try a few values for x and see if by solving that side of the equation you get the value of y. If you do, you found your equation.
You have a big advantage here... since you have the value of y when x = 0.
When x = 0, y = 9, that's a very important data to have to simplify your research.
Let's try the value of 0 for x in each of the given equations:
y = 18 + 10 (0) = 18 --- NO
y = 9 + 19 (0) = 9 --- YES! We can confirm with another value of x:
y = 9 + 19 (1) = 28 --- YES! Confirmed!
y = 9 + 19x is your answer!
