Answer:
y = 25x, proportional relationship
Step-by-step explanation:
Let "x" = number of hours read (replace with "h" if that's the variable your teacher wants)
Let "y" = number of pages read (you can use any other variables if you want)
Let's first calculate the slope using
with any two points, I'm going to use (2, 50) and (3, 75):

Our slope is m = 25.
Now we can use the point-slope form
with our slope and any point (I'll use (2, 50)) to figure out the equation:

Simplify:

Since the slope is positive, the relationship is proportional.
Amy:
8 + 5 + 6 + 11 + 4 + 6 +8 = 48
48 divide by 7 = 6.85
chelsea:
7 + 9 + 5 + 3 + 10 + 5 + 8 = 47
47 divide by 7 = 6.71
amy runs more on average.
both mean !
The equation that is in point-slope form for a line that goes through (2,-6) and has a slope of -3/4 is y+6=-3/4(x-2).
The equation for point-slope is y-y1=m(x-x1). So just take the given info and plug it in. Since the y-point is negative, it becomes a positive in the equation.
The argument is valid by the law of syllogism.
To find the cost per yard, divide the cost by the amount:
p: 6.25 / 6.5 = 0.96 --> The cost per yard is $0.96
r: 3 /4 = 0.75 --> The cost per yard is $0.75
b: 8.1 /8.5 = 0.95 --> The cost per yard is $0.95
s: 7.2 / 6 = 1.2 --> The cost per yard is $1.20
In order from cheapest to most expensive:
Red
Brown
Purple
Silver
Hope this helps.
