Answer:
The y-intercept is at y = 10.
Step-by-step explanation:
It will be between y = 14 and y = 7 because the corresponding x values are -2 and 1.
An increase of 3 units of x gives a decrease of 6 units of y fro the above values.
Then an increase of 1 ( 1 to 2) in x gives decrease in y of 2 (8 to 6). The other values show the same pattern.
So very unit increase in x, the y values change by -2.
So from x = -2 to 0 is +2 units for x and this will be -4 units for y so the y-intercept ( when x = 0) will be at y = 14-4 = 10
y-intercept is (0,10).
Answer:
The coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are 
Step-by-step explanation:
We need to find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)
The midpoint of line segment can be found using formula:

We have 
Putting values and finding midpoint

So, the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are 
15 boys and 16 girls....total is (15 + 16) = 31
probability that a boys name is drawn : boys/total ppl = 15/31
40x28
First take 0x8=0
Then take 40*8=320
Next, 20*0=0
Then, 40*20=800
Finally, add them all together to get 1120!
