1st- gained lost 800, gained 900
2- lost 400- gained 600
so in all she lost 1200
but then gained 1500
Question 1 would be 4 divided by 1/3 (A)
Question 2 would be 16 (A)
Question 3 would be 48 (B)
Question 4 would be 60 laps
Question 5 would be 1/15th
Hope this helps!! :D

Explanation:
Given that we have the slope and a point on the graph we can use the point slope formula to find the equation of the line.
Point-Slope Formula:
y
−
y
1
=
m
(
x
−
x
1
)
, where
m
is the slope of the line and
x
1
and
y
1
are x and y coordinates of a given point.
We can summarize the information already given:
m
=
−

x

y

Using this information, we can substitute these values onto the point-slope formula:
y

The equation above is the equation of the line in point-slope form. If we wanted to have the equation in
y
=
