Me i need to answer this before october for each table, identify the independent and dependent variables. represent the relationship using words, an equation, and a graph. number of chairs painted, p | paint left (oz), l 0 | 128 1 | 98 2 | 68 3 | 38 number of snacks purchases, s | total cost ,c 0 | $18 1 | $21 2 | $24 3 | $27 number of flights of stairs climbed, n| 0 | 1 | 2| 3 | elevation(ft above sea level),e |311|326|341|256| me  & you

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

, , , .

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

and the y-intercept is

The equation is given by

That is

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

, , , .

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

and the y-intercept is

The equation is given by

That is

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

, , , .

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

and the y-intercept is

The equation is given by

That is

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

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

265 words per minute

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

    200 words per minute

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
