Which equation best shows the relationship between x and y? y = x + 70 y = 5x + 60 y = 5x + 70 y = x + 60

OpenStudy (nuccioreggie):

@TrojanPoem

OpenStudy (trojanpoem):

Is that the complete question ?

OpenStudy (trojanpoem):

I think there is a graph or something

OpenStudy (nuccioreggie):

Shelly sells ice cream bars at the beach. In addition to a fixed salary, she earns a commission for each ice cream bar she sells. The table shows Shelly's total earnings, y, from selling x bars of ice cream: Ice Cream Sales and Earnings Number of Bars Sold (x) Total Earnings (dollars) (y) 0 60 1 65 2 70 3 75

@welshfella

OpenStudy (trojanpoem):

when x = 0 , y = 60 , when x = 1, y = 65 y = 5x + 60

OpenStudy (nuccioreggie):

so B

OpenStudy (trojanpoem):

yeah

OpenStudy (nuccioreggie):

OK TY

OpenStudy (nuccioreggie):

What is the initial value of the function represented by this graph? A coordinate grid is shown with x and y axes labeled from 0 to 7 at increments of 1. A straight line joins the ordered pair 0, 2 with the ordered pair 7, 5. 0 1 2 5

@TrojanPoem

OpenStudy (nuccioreggie):

OK SO THE CORRECT ANSWER IS B (:

OpenStudy (michele_laino):

here we have to apply this formula: \[\frac{{x - {x_1}}}{{{x_2} - {x_1}}} = \frac{{y - {y_1}}}{{{y_2} - {y_1}}}\] for example, if \((x_1,y_1)=(0,2)\), and \((x_2,y_2)=(7,5)\), then after a substitution, we can write: \[\frac{{x - 0}}{{7 - 0}} = \frac{{y - 2}}{{5 - 2}}\] please simplify

OpenStudy (nuccioreggie):

b

OpenStudy (michele_laino):

initial value is the \(y-\)coordinate of the initial point \((0,2)\)

OpenStudy (nuccioreggie):

sorry i ment A

OpenStudy (nuccioreggie):

ok so is it C INCLUDING YOUR HELP?

OpenStudy (michele_laino):

correct!
