we can mark points on the graph shown , check the image I have shared with this for the points .
Formula for slope =
So for Line A points are (1,3) and (0,-1)
So using t he formula slope is =
slope of line A =4
For Line B the points are (0,4) and (3,-5)
So using t he formula slope is =
slope of line B = -3

Andre picked up almost 253 pounds of apples from a total of 840 pounds.
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given are Jane, Andre, and Maria. All of them are picking apples such that Andre picks three times as many pounds as Maria. Jane picks two times pounds as Andre and the total weight of apples is 840 pounds
Assume that Maria took (x) pounds of apples.
Then, Andre will pick (3x) pounds of apples.
Finally, Jane will pick up (6x) pounds of apples.
The total weight of apples is 840 pounds.
Therefore, we can model the situation as follows -
x + 3x + 6x = 840
10x = 840
x = 84
So, Maria took 84 pounds of apples.
Now, the apples picked up by Andre = 3x = 3 x 84 = 252 pounds of apples
Therefore, Andre picked up almost 253 pounds of apples from a total of 840 pounds.

Andre picks 252 pounds of apples.
Further explanation:
Jane, Andre and Maria pick apples such that the apples picked by Jane are denoted by J, the apples picked by Andre are denoted by A and the apples picked by Maria are denoted by M.
The total weight of apples is 840 pounds.
Therefore, this can be written as,
......
Andre picks three times as many pounds Maria then ..
Jane picks two times pounds as Andre then ..
Substitute 3M for A in the equation to obtain relation between J and M as,
Now, substitute 3M for A and 6M for J in equation (1) then we get,
Therefore, Maria picks 84 pounds of apples.
Substitute the obtained value of as 84 in equation as,
Therefore, Jane picks 504 pounds of apples.
Substitute the obtained value of as 84 in equation as,
Therefore, Andre picks 252 pounds of apples.
Thus, the total quantity that Andre picks is .
