Answer:
slope-intercept form y= -2/3 x + 490 slope is -2/3 y intercept is (0.490)
Step-by-step explanation:
2x+3y= 1470
3y= 1470-2x
y= 1470/3- 2/3 x
y= -2/3 x+ 490
slope is -2/3 and y intercept is 490 when x =0
the graph represent the amount of sandwiches that Sal's shop sold, where x is the number of sandwiches and y is the number of wraps sold. so that x won't exceed 735 sandwiches : 0≤x≤735 and 0≤ y≤490.
<u>total profit is 1593.</u>
2x+3y= 1593
y= -2/3 x + 531
similar : the two functions have the same slope -2/3
difference: 0≤ y≤531
0≤x≤796.5
the two line are parallel
