Write the function in slope-intercept form. then graph the function.
2x - 5y = -6

2x - 5y = -6 first subtract the 2x to get 
-5y=-2x-6 and then multiply each side by a -1 to get
5y=2x+6 divide by 5
y=2/5x+6/5

To graph this just put a point on 6/5 on the y axis then to find the next point move over to the right 2 and up 5. After you have two points draw the line connecting them.

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
