1) Subtract 6x from both sides. -3y= -9-6x
<span>2) Divide both sides by -3. y= 3+2x </span>
<span>2) Put it in slope-intercept form: y=mx+b. y= 2x+3 </span>
<span>Final answer: y=2x+3</span>
Wait is this a photo of a test? If so sorry I can't help you.
Answer:
The 8th number is -9
Step-by-step explanation:
With an average, the sum of the seven numbers divided by 7 is 15.
In order to add an 8th number, we set up

10/190 = 13/z...if there directly proportional, make a proportion
cross multiply
(10)(z) = (190)(13)
10z = 2470
z = 2470/10
z = 247 <==
B. the x and y values were not identified correctly
