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

Answer:
2.5; 2.5
Step-by-step explanation:
slope m = (y2-y1)/(x2-x1) (or use the graph and count rise over run)
m = (10-5)/(4-2) = 5/2 or 2.5
The slope of the line is 2.5. This means that 2.5 mm of rain falls every hour
