Answer:400
Step-by-step explanation:
2x + 3y = 1200
3y = -2x + 1200
y = (-2x/3)x + 1200/3
the slope is -2/3x the y intercept is 40
She is 12 feet above the ground.
Answer:
7 feet
Step-by-step explanation:
becuse you do 15-8 and get 7
The first thing you need to do is calculate the slope. pick 2 of the ordered pairs.
i'll use (1, 4) and (0, 6)
m = (6 - 4)/(0 - 1)
m = (2)/(-1)
m = -2
so the slope is -2. slope intercept form is written as y = mx + b and you have one part of that equation
y = -2x + b
to find b, use one of the selected points. i'll use (0, 6).
(6) = -2(0) + b
6 = b
b = 6
therefore:
y = -2x + 6
