Y = mx + b
4 = m(248) + b
6 = m(372) + b
subtract the two equations to get
-2 = m(-124) + 0
m = 1/62
Then plug in m into one of the equations to find b
4 = (1/62)(248) + b
4 = 4 + b
b = 0
So the equation is
y = (1/62)x + 0
or
y = (1/62)x
or
y = x/62
edit: I totally didn't use point slope. It should be
y + 0 = (1/62)(x + 0)
or y = (1/62)x
(since b is 0, that means she started driving directly at home)

2) 150mi/1.25hr = Xmi/5hr
750mi/1.25 = X
X = 600miles
13 lbs shared between 3 batches . . .
13/3 = 4 1/3 lbs each
The two whole numbers would be 4 and 5
Answer:
sorry bro just wanted the points but thanks have a great day
Step-by-step explanation:
Add up all of the sides and you will get the ratio
Answer:
11
Step-by-step explanation:
Constant of proportionality, k, is the ratio of the quantity of variable y to the quantity of variable x.
Using a point on the line, (4, 44),
Constant of proportionality, k =
.
Constant of proportionality of the graph is 11.
