    Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

    1)Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.

    2)Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.

    they want you to solve 2x + 3y = 1,470 for y. Do you know how?

    Part a) 2x + 3y = 1,470 3y = -2x + 1470 y = (-2x + 1470 ) / 3 y = -2/3 * x + 1470/3 y = -2/3 * x + 490 slope is -2/3 y intercept is 490 Part b) Plot the y intercept (0,490) and the x intercept (735,0) Connect the two intercepts with a straight line Part c) f(x) = -2/3 * x + 490 The graph shows the number of wraps sold as a function of the number of sandwiches sold.

    x = 735-3y/2

    Part e) 2x + 3y = 1593 3y = -2x + 1593 y = -2/3*x + 1593/3 y = -2/3*x + 531 The graphs are similar in that they are parallel . They are dissimilar in that they have different y intercepts. Part f) not enough information given. Directions say 'below is a graph'
