Answer:
Hence (3, -3) is on the given line y = -2x + 3
Step-by-step explanation:
For a point on the Line, It must Satisfy the Equation of a line
Therefore for
For (-2,-1)
Substitute x = - 2 and y = -1 in above equation
Left Hand Side = y
= -1
Right Hand Side = -2 × (-2) +3
= 4 +3
= 7
Left Hand Side ≠ Right Hand Side
Not Satisfied
Hence (-2,-1) is NOT on the given line
For (3, -3)
Substitute x = 3 and y = -3 in above equation
Left Hand Side = y
= -3
Right Hand Side = -2 × (3) +3
= -6 +3
= -3
Left Hand Side = Right Hand Side
Satisfied
Hence (3, -3) is on the given line y = -2x + 3
For (3, 3)
Substitute x = 3 and y = 3 in above equation
Left Hand Side = y
= 3
Right Hand Side = -2 × (3) +3
= -6 +3
= -3
Left Hand Side ≠ Right Hand Side
Not Satisfied
Hence (3,3) is NOT on the given line
For (-3,-9)
Substitute x = -3 and y = -9 in above equation
Left Hand Side = y
= -9
Right Hand Side = -2 × (-3) +3
= 6 +3
= 9
Left Hand Side ≠ Right Hand Side
Not Satisfied
Hence (-3,-9) is NOT on the given line
Answer:
2.3 × is 20,000 times greater than 1.15 ×
Step-by-step explanation:
Given as :
The first number= x = 2.3 ×
The second number= y = 1.15 ×
Let The first number is z times greater than second number
i.e x = z × y
Or, z =
Or, z =
Or, z = 2 ×
∴ z = 20,000
So,The first number is 20,000 times greater than second number
Hence, 2.3 × is 20,000 times greater than 1.15 ×
