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

y=-2x+3

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 from: Quest

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
