Find the slope and y-intercept of the following linear equation. Express the y-intercept as a coordinate pair y = 7x

slope: 7

y intercept (0 , 0)

Step-by-step explanation:

y = 7x

equation of line: y = mx + b      m: slope     b: y intercept

slope = 7

y intercept: 0    (0 , 0)

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
