Q

When solving the problem:
2(3x-10)/11=8 (11 is under 2(3x-10) and the =8 is beside them both.)
Do you solve the brackets first or take 11 out of the equation first.

A

Take 11 out of the equation first.

Q

What does it mean for a graph to be constant?

A

The inclination doesn’t change.

17
Q

What does it mean for a graph to be not constant?

A

The inlination changes.

18
Q

What is an undefined graph?

A

When the line is vertical.

19
Q

Is it rise over run or run over rise?

A

Rise over run.

20
Q

What is the y intercept?

A

When the line crosses the y axis.

21
Q

What is the x intercept?

A

When the line crosses the x axis.

22
Q

What formula is used to calculate the slope?

A

x2-x1

23
Q

When told to graph a line how do you?

A

Use rise over run. If the formula is
y=1/4x-1
1/4 is your slope.
-1 is your initial value
You will rise 1 point on the graph and run 4.
If your slope is a full number like 6. Add 1 as the denominator. Like this 6/1.

24
Q

If points on a graph were (-3,5) (-3,-7) (-3,4) (-3,0). What would the rule be?

A

The rule would be -3 because every single coordinate has the number -3 in the x spot. So x=-3
