6x - 2y = 18
-2y = -6x + 18
y = -6x/-2 - 18/2
y = 3x - 9
comparing to y = mx + c,
m = 3,
Slope = 3
It’s -37 because -20-17=-37
2.8 lbs
Explanation- 16-6.8=9.2
12-9.2=2.8
Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:
The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct
