Answer:
45 carrots and 21 potatoes
we can easily find how many carrots by looking at the x-axis that has a straight line on 45 which is indicate the amount of carrots.
For potatoes we need to find the y value at the interception ( 28, 21 ) , then our y is 21, which is 21 potatoes.
To know the coordinate, we should find the gradient of the graph which is M = 15/20 , then we look at the given answer that closes to the y coordinate of the interception which is around 20 to 25, only 21 is can be used in this answer. To check our justification, we can substitute y = mx + c which become 21 = 0.75x + 0
, our x is 28 which is true because when our y is 21 , the y should be in the middle of 25 to 30. The constant is 0 because the straight line is started at 0 and doesn't shifted yet.
