ANSWER TO QUESTION 7

Independent Variable: Number of Chairs Painted(p)

Dependent Variable: Paint Left(L)

To represent the relationship using a graph, we draw two perpendicular axis, wth Number of Chairs Painted(p) on the horizontal axis, and Paint Left(L) on the vertical axis.

Then we plot the points

$(0,\:\:128)$ , $(1,\:\:98)$ , $(2,\:\:68)$ , $(3,\:\:38)$ .

Using a straight edge, we draw a straight line through the points as shown in the diagram attached.

From the graph the slope is given by

$Slope=\frac{60}{-2}=-30$

and the y-intercept is

c=128

The equation is given by

L=mp +c

That is

L=-30p +128

In words, Paint level is reducing at a rate of oz

ANSWER TO QUESTION 8

Independent Variable: Number of snacks purchased(s)

Dependent Variable: Total Cost(c)

To represent the relationship using a graph, we draw two perpendicular axis, with Number of snacks purchased(s) on the horizontal axis, and Total Cost(c) on the vertical axis.

Then we plot the points

$(0,\:\:18)$ , $(1,\:\:21)$ , $(2,\:\:24)$ , $(3,\:\:27)$ .

Using a straight edge, we draw a straight line through the points as shown in the diagram attached.

From the graph the slope is given by

$Slope=\frac{3}{1}=3$

and the y-intercept is

c=18

The equation is given by

C(s)=ms +c

That is

C(s)=3s +18

In words, the Total cost increases is reducing at a unit rate of

ANSWER TO QUESTION 9

Independent Variable: Number of flight of stairs climbed(n)

Dependent Variable:Elevation (ft above sea level),E

To represent the relationship using a graph, we draw two perpendicular axis, with Number of flight of stairs climbed(n) on the horizontal axis, and Elevation (ft above sea level),(E) on the vertical axis.

Then we plot the points

$(0,\:\:311)$ , $(1,\:\:326)$ , $(2,\:\:341)$ , $(3,\:\:356)$ .

Using a straight edge, we draw a straight line through the points as shown in the diagram attached.

From the graph the slope is given by

$Slope=\frac{15}{1}=15$

and the y-intercept is

c=311

The equation is given by

E(n)=mn +c

That is

E(n)=15n +311

In words, the unit rate of rising above sea level is
