Answer:
-4
Step-by-step explanation:
We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.
The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.
We have the gradient, so we can put it in the equation:
y = x/2 + c
We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.
3 = 6/2 + c
3 = 3 + c
c = 0
Therefore the equation for our line is y = x/2.
We can now put in the y coordinate we were given to work out the corresponding x coordinate:
-2 = x/2
x = -4
Therefore n is -4.

Uhm the third one number 3
The Answer is 20. Just take my word for it its 20
Answer:45.3 ft
Step-by-step explanation: Is your answer.
0.35 + 0.3x > 0.45 + 0.2x
0.3x - 0.2x > 0.45 - 0.35
0.1x > 0.1
x > 1...so it is better to use B when ur talking for more then 1 minute
