PLEASE I NEED HELP ANSWER (05.03)Bella works at a shoe store. In addition to a fixed salary, she earns a commission for each pai
r of shoes that she sells. The table shows Bella’s total earnings , y (in dollars), from selling x pairs of shoes: Shoe Sales and Earnings Pairs Sold (x) Total Earnings (y) 1 95 2 110 3 125 Which equation best shows the relationship between x and y?
To know the equation represents the relationship of x and y first solve the slope of the relationshipm = ( y1 - y2) / ( x1 - x2 )m = ( 95 - 110) / ( 1 - 2 )m = 15 using point ( 1 , 95 ) solve the y intercept y = mx + b 95 = 1(15) + bb = 95 - 15b = 80 and this represents her fixed salary so the equation is y = 15x + 80
