To find the slope, you find the change in y-values over the change in x-values.
Your first point is: (5,-3)
Your second point is (8, -5)
Your x-values are: 5 and 8
Your y-values are -3 and -5
The equation to find slope is: slope = (y2-y1)/(x2-x1)
- The 2s and 1s indicate which point the values belong to, it makes sure that you align the right x-value with its correct y-value. It doesn't matter which point you assign as 1 or 2, as long as the values match
- So, x-value 5 will match with y-value -3, and x-value 8 will match with y-value -5
Now you plug in out values :
slope = (y2-y1)/(x2-x1)
slope = (-5-(-3))/(8-5)
slope = (-2)/(3)
slope = -2/3
13 3/4 = ((13x4)+3)/4 = 55/4
1 2/3 = ((1x3)+2)/3 = 5/3
55/4 / 5/3
(55x3)/(5x4)
165/20
33/4
8 1/4
Answer:
12 boys
Step-by-step explanation:
Multiply the ratio numbers by 6 and you have
boys : girls = 2 : 3 = 12 : 18
There are 12 boys in the class.
Answer:
1.4
Step-by-step explanation:
Divide 2.8 by 2 because of 2 minutes to make it 1 minute.
Answer:
6 cups
3 cups
5 tsp.
2 tsp.
2 tsp.
8 egg whites
4 cups
1 cup
Step-by-step explanation:
Simply multiply the amounts by 4. (12 x 4 = 48)
Ex. for the first item: flour ......
1 1/2 cups = 1.5 cups
1.5 x 4 = 6 cups
