Find an equation of the line parallel to x=5y-9 and passing through (2,-4). express in standard form.
me .

y = (1/5)x - (22/5)

Step-by-step explanation:

Parallel means they have the same slope.

x = 5y - 9

+9        +9

x + 9 = 5y

(1/5) (x + 9) = y

y = (1/5)x + (9/5)

m = (1/5)

y = mx + b

y = (1/5)x + b

-4 (5/5) = (1/5)(2) + b                   *(5/5) is equivalent to 1

-(20/5) = (2/5) + b

-(2/5)  -(2/5)

-(22/5) = b

it is true

step-by-step explanation:

all the combinations add up i used   calculator

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
