It is -9. Rise over run. 9 up, 1 to the left, 9/1 = 9. Because the line goes down to the right, it is negative.

Please put me as the brainiest.

What is the equation for this graph
igomit [66]

Answer:

y = 50x

Step-by-step explanation:

To find the equation of a graph, we follow the formula: y = mx + c where m is the slope of the graph and c is the y-intercept. For the slope, I will be using the points (0,0) and (2,100)

Slope = \frac{rise}{run}

          = \frac{100-0}{2-0}

          = \frac{100}{2}

          = 50

Based on the graph, the y-intercept is 0. Thus the equation of the line would be:

y = 50x + 0

y = 50x

ad-work [718]

Answer:

60

Step-by-step explanation:

12=2⋅2⋅3

15=3⋅5

We see that they both share 3 is their LCM.

We divide each number by their LCM.

123⇒4

153⇒5

We multiply these two quotients and the LCM to get our final answer:

3⋅4⋅5=60

That is our answer!

Please answer 27 and 28
valina [46]

Answer:

27: 29.93 Seconds

28: 28 ° Fahrenheit

Step-by-step explanation:

Number #27:

Given:

#1 Lap = 14.76 seconds

#2 Lap = 15.17 seconds

Steps:

1. Use the algorithm method.

      1

14.76

+ 15.17

-------------

Answer: 29.93 seconds  

--------------------------------------------------------------------------------------

Number #28:

Given:

Wind Chill Temperature: - 18 ° F

Actual Temperature: 10 ° F

Steps:

1. Subtract 18 from 10.

Answer: - 28 ° degrees fahrenheit

Note: Whenever there is a negative sign next to a temperature, it means it's below freezing as the below freezing temperature is 0  ° Fahrenheit. This also means subtraction. In this case, you would subtract the negative amount from the positive amount creating an equation, that equation represents the degrees in fahrenheit:

10 - 18

The result should be -28.

This also means that the difference between both temperatures is 28 degrees. Wind chill creates a feeling of higher temperatures even though the actual temperature in the atmosphere was 10 ° F in this specific land structure.

Hope this helps,
