For this one use the slope formula, (y2-y1)/x2-x1)
Just to have them in one place, here are the ordered pairs
(-1,-2) (2,2)
You can do these in any order, here is how I did the problem:
(2--2)/2--1)
Your y intercepts are 2 and -2
The x are 2 and -1
Now reduce. Since you are subtracting a negative, it turns into a positive.
(2+2)/(2+1)
4/3
There is our slope: rise 4 run 3 or as a fraction 4/3.
Hope this helps!
By the picture it looks like they keep multiplying it by 3 so you just do 90*3 =270 and 270*3=810 so your next to answers should be 270 and 810
Answer:
a.) 16
b.) 8
Step-by-step explanation:
a. how much lower was the 6am temperature in Nome than in Wyoming
Essentially this question is asking us to find the difference of the temperatures of Nome and Wyoming at 6am
Temperature of Nome at 6am: -31
Temperature of Wyoming at 6am: -15
Difference between two temperatures: -31 - (-15)
The two negative signs cancel out and the sign changes to +
-31 + 15 = -16
The temperature in Nome was 16 degrees lower then in Wyoming
b. At noon the temperature of Boston had risen by 14 degrees. what was the temperature of boston at noon.
All we have to do for this one is add 14 to the temperature of Boston at 6am. ( This is because the question tells us the temperature has risen 14 degrees by noon )
-6 + 14 = 8
At noon the temperature would be 8 degrees in Boston.
The answer should be reported as... multiplying the length by the width if the length and the width are different but if not then multiply length by length
Please mark as brainliest!
