Question

Draw the graph of equation X upon 4 + Y upon 5 is equal to 1.

Use the graph to find:
i) X, the value of x, when Y is equal to 10.
ii) Y, the value of Y, when x is equal to 8.
#This has to be drawn in the proper graph only.
#And no nonsense things to be put up.
If u know the answer give it or else MOVE..​

Answer 1

=>x/4 +y/5 = 1 => 5x + 4y= 20 ----(1)

i) => 5x + 4(10) = 20 => 5x = 20-40 => 5x = -20

x = -4

ii) => 5(8) + 4y = 20 => 4y = 20-40 => 4y = -20

y = -5

Answer 2

Answer:

=>x/4 +y/5 = 1 => 5x + 4y= 20 ----(1)

i) => 5x + 4(10) = 20 => 5x = 20-40 => 5x = -20

x = -4

ii) => 5(8) + 4y = 20 => 4y = 20-40 => 4y = -20

y = -5
