Answer:
x = 0.5
Step-by-step explanation:
2.2X + 2.2 = 1.1
subtract both sides by 2.2
2.2X = -1.1
divide both sides by 2.2
we get x = 0.5 or 1/2
Answer:

Step-by-step explanation:
Let
and swap x and y:

Then, rearranging for y:



Answer:
y=-3/7x+2
Step-by-step explanation:
first formula (Slope): y2-y1/x2-x1
-1-2/7-0= -3/7
second formula (point slope): y-y1=m(x-x1)
y-2=-3/7(x-0)
(distribute the -3/7)
y-2=-3/7x-0
(add 2 to both sides)
y=-3/7x+2
Answer: The answer is...9 and 1/2!
Step-by-step explanation: Subtraction of course!
