Answer:
Option 2
Step-by-step explanation:
The quantities are not proportional because the line of the graph is both passing through the origin. It might have been proportional if it was passing through the origin.
Answer:
each person (including Alana) gets 25mL of water
Step-by-step explanation:
since there is 4 ppl, and 100mL of water, you divide 100/4. Therefore, each person gets 25mL of water:)
Answer: B is what 6 x +4 = to 4bx - 2 is 6x plus 4 = to 24 then 4bx - 2 is YA so b is Y

Answer: A) -2</h3>
==========================================
Explanation:
Let's find the slope of line AB
m = (y2-y1)/(x2-x1)
m = (2-7)/(-6-4)
m = (-5)/(-10)
m = 1/2
The slope of line AB is 1/2
To get the slope of BC, we flip the fraction and the sign to get the perpendicular slope
1/2 becomes -2/1 or simply -2
----------
Slope of AB = 1/2
Slope of BC = -2
Notice how the two perpendicular slopes multiply to -1.
We know they are perpendicular because the four angles of any rectangle are always 90 degrees each.
Answer:
y-7=1/4(x+5)
Step-by-step explanation:
y-3=-4(x+2)
y=-4x-8+3
y=-4x-5
-----------
y-y1=m(x-x1)
y-7=m(x-(-5))
y-7=m(x+5)
perpendicular means negative reciprocal of the slope,
so the slope will be 1/4
y-7=1/4(x+5)
