Answer:

1. 1/2

Step-by-step explanation:

With a graph that has easily see-able points, slope can be calculated with rise over run, or change in y divided by change in x

$\frac{2-1}{2-0} =\frac{1}{2}$

What does the $\frac{1}{2}$ mean? From any point, the next point will be up one and over to the right two. Since the graph is going from bottom left to top right, it is positive.

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Step-by-step explanation:

Slope = y2 - y1/x2 - x1

=> 2 - 1/2 - 0

=> 1/2

Hence,

Option A is correct

Pls help me that would be great

No. No. It is not linear because the slope has to be able to be plugged in to any x, y coordinates and be placed on the line.

Which ordered pair represents the y-intercept of the graph of the equation y = -3x - 9?

Mnenie [13.5K]

------------------------------------------------------------------------------------------
Equation
------------------------------------------------------------------------------------------
y = -3x - 9

------------------------------------------------------------------------------------------
Option 1
------------------------------------------------------------------------------------------
If I substitute x = -9, I should get y = 0

When x = -9
y = -3 (-9) - 9
= 18 (I did not get 0, wrong)

------------------------------------------------------------------------------------------
Option 2
------------------------------------------------------------------------------------------
If I substitute x = -3, I should get y = 0
y = -3(-3) - 9
y = 9 - 9
y = 0 (Yes, I got 0, correct)

------------------------------------------------------------------------------------------
Option 3
------------------------------------------------------------------------------------------
If I substitute x = 0, I should get y = -3
y = -3 (0) - 9
y = 0 - 9
y = -9 (I did not get -3, wrong)

------------------------------------------------------------------------------------------
Option 4
------------------------------------------------------------------------------------------
If I substitute x = 0, I should get y = -9
y = -3 (0) - 9
y = 0 - 9
y = -9 (Yes, I got -9, correct)

------------------------------------------------------------------------------------------
Answer: (-3, 0) and (0, 9) are ordered pairs of the equation (Answer B, D)

This question is like impossible idk

7nadin3 [17]

If the problem was written x + 4x. We would know to add like the coefficients together and get 5x same thing with the radicals.

$\sqrt{3} + 4 \sqrt{3} = 5 \sqrt{3}$

A person can pay $14 for a membership to the history museum and then go to the museum for just $5 per visit. What is the maximum

umka2103 [35]

Hi there!
First we subtract 44-14 leaving us with 30. 5x6 = 30
Therefore, a member can visit a history museum 6 times to equal a total cost of $44.
In a different situation:
If the person has already paid the $14, and that doesn’t count as a visit, then a person would have to visit a museum 8 times to get a total of $45. Considering this is a real-world problem.
I hope this helps and have a good day :) !
