You present a lot of questions here, especially considering that you aren't sharing any work (or any thoughts) of your own. As a courtesy I'll help you get started out:
"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." Solve this equation for y: 3y = 1470 - 2x, or
1470 - 2x
y = ---------------
3
The slope of this line is -2/3. This is the coefficient of x in the above equation.
The y-intercept is 1470/3, or 490. This represents the profit (from wraps) when zero sandwiches are sold (that is, when x = 0).
Please start on the next part of this long question. Share your work and ask questions if necessary.
