What is the slope of the line represented by the data table?
djyliett [7]
A) Slope:    (y2 - y1) / (x2 - x1)

You can use point  (-1, -6) and (0, -8)

Slope =    (-8 - -6) /(0 - -1) =   (-8+6)/(0+1) = -2/1  = -2.

Slope = -2.

b) Point (0, -8)  is the point such that  x = 0,  and y = -8, this point represents the vertical intercept  of the equation.  The point where the line cuts the y axis.

Julianne opens a dance studio. Her start-up costs for the building, advertising, and supplies $52,000. Each day, she spends $650
Yuki888 [10]

The equation is:  960d-650d=52000 and Julianne will begin making a profit after 168 days.

<em><u>Explanation</u></em>

Her total start-up cost is $52,000.

Each day, she spends $650 on operating costs (like utilities and wages) and she earns $960 per day from her students' lesson fees.

If the number of days to overcome the start-up cost is  d , then

the total operation cost spent in  d days = \$650d and

the total students' lesson fees earned in  d days = \$960d

<em><u>Part A:</u></em>   The equation to represent the situation will be:   960d-650d=52000  

<u><em>Part B:</em></u><em> </em><em>  </em>Julianne will begin making a profit when....

960d-650d>52000\\ \\ 310d>52000\\ \\ d>\frac{52000}{310}\\ \\ d >167.741... \approx 168

So, Julianne will begin making a profit after 168 days.
