Answer:
15
Step-by-step explanation:
The slope =
This means that when the caterpiller moves 2 units to the right, it moves 3 units up. Since 42/3 = 28/2 = 14. this happens 14 times from (-3, -4) to (25, 28). Counting the starting point (-3, -4) we get 14 + 1 = 15 points with integer coordinates.
In order to know the answer, you would have to set up a system of equations:
Given that type A coffee costs $4.15 per pound
(4.15x)
Given that type B coffee costs $5.25 per pound
(5.25y)
And that the total cost of it all was $642.60
Also, the amount of pounds, represented by x and y add up to 150 pounds total:
