Where do I start when I am graphing a line?
at the y-intercept!
100
If I am graphing a system of equations. What button do I hit first?
y=
100
What's the first thing I would do to solve this problem? y = 2x -4x + 5y = 6
Rewrite the second equation, substitute 2x in for y.
100
In the problem 6x + 3y = 14 2x - 3y = 10 What would I do first?
Cross out the 3ys
100
What is 9x2?
18
200
If my slope is positive, should I go up or down?
Up
200
After both equations are entered, what do I do next?
Hit graph
200
In the problem -4x + 5(2x) = 6 What would I do next?
Multiply 5 x 2x to get 10x
200
In the problem 6x = 14 2x = 10 what would I do next? What would be my solution?
Add the remaining variables and coefficients 8x = 24

What is 7x9
63
300
If my slope is negative, should I go up or down?
Down

Once I hit 2nd trace, what number do I hit on the menu?
5

In the problem -4x + 10x = 6, what would I do next?
Combine like terms, -4x + 10x = 6x
300
In the problem 8x = 24 what would I do next? What would x equal?
Divide both sides by 8. x = 3

What is 11 x 11
132

Describe how I would graph this line: y=2/3x + 5
Start at 5 on the y axis. Go up two and over(to the right) three. Plot the point. Connect points with a line with arrows.

What are the two parts to the answer? (What does the intersection point say?)
x = y =
400
In the problem 6x = 6 what do I do next? what does x equal?
Divide both sides by 6. x = 1
400
In the equation 6x + 3y = 14 2x - 3y = 10 if x = 3, how would we find the value of y? what is the value of y?
Plug in the value of x into one of the equations. y = 10.6

What is 10x12
120
500
If I have a whole number, what number goes underneath?
1

Solve it! y = 1/3x - 3 y = -x + 1
(3, -2)

x = 1 y=2x What is the value of y? What is the ordered pair?
y= 2 ordered pair (1,2)
