Step-by-step explanation:
Given equations are 10x+2y=56 and 8x+3y=49
To fill the table for each equation by using the exact values in the table :
10x+2y=56
put x=0 in above equation we get
10(0)+2y=56
2y=56
Therefore (0,28)
put y=0 in the given equation 10x+2y=56 we get
10x+2(0)=56
10x=56
Therefore (,0)
10x+2y=56
x y

For
8x+3y=49
put x=0 in above equation we get
8(0)+3y=49
3y=49
Therefore (0,)
put y=0 in the given equation 8x+3y=49 we get
8x+3(0)=49
8x=49
Therefore (,0)
8x+3y=49
x y
