Substitute in the points. It doesn't matter if they ar pe variables or not, since the variable b is used already in the equation, making it possible to find.
Substitute in the y value for the y in the equation and do the same for the x.
-3=2b+b
-3=3b
-1=b
b is -1.
Hope this helps!

Step-by-step explanation:
1. So first you have to cross multiple the two terms
2.Solve the algebraic equation
By dividing with 12 on both sides
(Note :That's a 32 in the picture sometimes i really write bad)
Answer: -3x+1 and y column will have the same answers because y = -3x+1
<u>-3x+1</u>
-3(-2)+1 = 6+1 = 7
-3(-1)+1 = 3+1 = 4
-3(0)+1 = 0+1 = 1
-3(1)+1 = -3+1 = -2
-3(2)+1 = -6+1 = -5
<u>(x, y)</u>
(-2, 7)
(-1, 4)
(0, 1)
(1, -2)
(2, -5)

Answer:
13 pencils.
Step-by-step explanation:
Let x be the pens and y be the pencils
Given:
Brian purchased pens for 75 cents each and pencils for 40 cents each he bought total of 22 writing utensils for $11.95.
Total pens and pencils is 22
So, ----------------(1)
And he bought all utensils for $11.95. and each pen for 75 cents and pencils for 40 cents.
------------(2)
solve equation 1 and equation 2 for x and y.
From equation 1.
----------------(3)
put y value in equation 2.
Now substitute x value in equation 3.
So, he buy 13 pencils.
