Answer:
1. slope: (y2-y1)/(x2-x1)
(6,38), (9,32)
(32-38)/(9-6) = -6/3 = -2
38 = -2(6) + b
38 = -12 +b, b = 50
y = -2x + 50
2a. Slope = -80, the slope means how many cars left per hour after closing. Y- intercept = 600, cars in lot during closing.
2b. use the equation: y = -80x + 600
Plug in 3 into the equation
y = -80(3) + 600, y = -240 + 600, y = 360 cars
2c. For it to have 0 cars, plug in 0 for y
0 = -80x + 600
-600 = -80x, solve for x
x = 7.5 hours
Answer:
(-3,6)
It is -3 on the x line and 6 on the y.
Hope this helps!
Answer:
X=7/6y+-1/3
Step-by-step explanation:
It will be hard for me to demonstrate the equation
The midpoint of a line segment is simply the average of the coordinates.
If you have endpoints (x1,y1) and (x2,y2) the midpoint is:
mp=((x1+x2)/2, (y1+y2)/2)
The slope on a vertical line will be 0
