Math

Question 1

If the line in the graph is going to the left will the slope be positive or negative?

Answer 1

Negative.

Question 2

If the line in the graph is going to the right will the slope be positive or negative?

Answer 2

Positive.

Question 3

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.

Answer 3

Take 11 out of the equation first.

Question 4

Is x the independant or dependants variable?

Answer 4

Independant.

Question 5

Is y the dependant or independant variable?

Answer 5

Dependant.

Question 6

Does a partial graph go throught the origin (0,0)?

Answer 6

No, it does not.

Question 7

What is the rule for a partial graph?

Answer 7

y=ax+b

Question 8

What does ‘b’ mean in a graph?

Answer 8

Inital value.

Question 9

What does ‘a’ mean in a graph?

Answer 9

Slope.

Question 10

Does a direct graph go through the origin (0,0)?

Answer 10

Yes, it does.

Question 11

What is the rule for a direct graph?

Answer 11

y=ax (because the inital value is 0)

Question 12

Does a zero graph go through the origin (0,0)?

Answer 12

No.

Question 13

What is the formula for a zero graph?

Answer 13

y=b

Question 14

What is another letter used in the place of x?

Answer 14

n.

Question 15

What is another letter used in the place of y?

Answer 15

c.

Question 16

What does it mean for a graph to be constant?

Answer 16

The inclination doesn’t change.

Question 17

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

Answer 17

The inlination changes.

Question 18

What is an undefined graph?

Answer 18

When the line is vertical.

Question 19

Is it rise over run or run over rise?

Answer 19

Rise over run.

Question 20

What is the y intercept?

Answer 20

When the line crosses the y axis.

Question 21

What is the x intercept?

Answer 21

When the line crosses the x axis.

Question 22

What formula is used to calculate the slope?

Answer 22

x2-x1

Question 23

When told to graph a line how do you?

Answer 23

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.

Question 24

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

Answer 24

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