I take the points that you gave. Let named A(0,-3) and B(2,1)
The slope coefficient is S= (yb-ya)/(xb-xa)
S= (1-(-3))/(2-0) => S= (1+3)/2 = 4/2= +2 => S= +2
The correct answer is positive slope
Good luck!!!
Answer:
as we know Sara need 8 tube in 3 experiment
she will use 2 tube in 1 experiment
now she have 6 tube in other experiments
so the question said to find how many tube were used in both experiment equally so 3,3 test tube were needed for each of the other two experiment
Step-by-step explanation:
total tube=8 (3 experiment)
used =2tube (1 experiment)
remaining=8-2=6
now ,
dividing 6 into 2 equal part
so,=6/2=3
so 3 tube were used in 2nd experiment and 3in 3rd experiment
Multiply all the numbers by what you see on the screen and the six the side and then divide it into a equal amount.
It’s the first one because the parabola is open
