First we need the slope, which we can get using (y2 - y1) / (x2 - x1)
Plug in our coordinates and we get
(15 - 12) / (2 - -4)
3 / 6
1 / 2
So, our slope is 1/2.
Then, we take 1/2 of one of our x values, say, 2, and we get 1. How do we go from 1 to 15? We add 14. So our y - intercept is 14.
All this plugged into y = mx + b gives us the equation y = 1/2 x + 14
Answer:
C
Step-by-step explanation:
x = 12.5832
x = 12.6
Girls:boys=5:4
So girls=5x
Boys=4x
total students=36
5x+4x=36
9x=36
x=4
So girls are=5x=5×4=20
Boys are=4x=4×4=16
x = 18.5, i am sorry if this is wrong
Here are some solutions: (there are actually an infinite amount of them)
x = 0 , y = 7
x = 1 , y = 8
x = 2 , y = 9
x = 3 , y = 10
x = 4 , y = 11
x = 42 , y = 49
x = pi , y = pi + 7
