Jay graphed the line y = x-6 on a coordinate plane. He drew an image of the line 3 units to the right of the original line. What is the same about the two lines?

Answers

The lines are parallel, because they have the same gradient but are just in different positions ie. y = x-9.

Answer:

No, he is not correct. Jay drew a line through the origin, but the line did not connect all three points. Not all the points lie on the line, which is necessary for a proportional relationship.

Step-by-step explanation:

It's the sample response.

Solve the equation
-3 2/5 + b = 8 1/5

Answers

add 3 and 2/5 to both sides
3+2/5-3-2/5+b=8+1/5-3-2/5
0+b=8-3+1/5-2/5
b=5-1/5
b=4+5/5-1/5
b=4+4/5
b=4 and 4/5

I think of two numbers, x and y
x-y is half of x+y
Write x in terms of y

Answers

You said that (x - y) is half of (x+ y) .  I can work with that.

(x - y) = 1/2 (x + y)

x - y = 1/2 x + 1/2 y

Multiply each side by 2 :

2x - 2y = x + y

Subtract 'x' from each side:

x - 2y = y

Add 2y to each side:

x = 3y

They can be ANY two numbers, as long as 'x' is triple whatever 'y' is.

Let's try a couple:

x = 18, y = 6
(x - y) = 12
(x + y) = 24
12 = 1/2 of 24x
yay !

x = 30, y = 10
(x - y) = 20
(x + y) = 40
20 = 1/2 of 40
yay !

x = 3π, y = π
(x - y) = 2π
(x + y) = 4π
2π = 1/2 of 4π
yay !



X-y =x+y all over 2
Add the y onto the other side making x = x+y all over 2 +y
Then you times everything by 2
2x = x+2y
Subtract x from both sides giving you
X=2y
