Question

PLEASE HELP 60 POINTS!!!!!!Sal’s Sandwich Shop sells wraps and sandwiches as part of its lunch specials.

Answer 1

2x + 3y = 1,470

To solve using the slope intercept method, we need to solve for y.

First, subtract 2x from each side.

3y = -2x +1470

The, we need to divide both sides of the equation by by 3 to solve for y

y = -2/3 x + 490.

We know the y intercept is 470, which means on the y axis we place at point at positive 490.  The slope is -2/3.  We go down 2 units and over to the right 3 units and place a point.  We draw a line connecting these two points extending only to the right until it reaches the x axis. We cannot have negative x because we cannot sell negative lunch specials.  We cannot have negative y, because y is the number of specials sold.
