The equation of a line is y=-2/3x-1 what is the equation of the line that is perpendicular to the first line and passes through (-4,3)

Given y=-2/3x-1, please present this as y=(-2/3)x-1 for clarity regarding the slope. Any line perpendicular to this line must have the slope 3/2.

Thus, the equation of the new line is

y - 3 = (3/2)(x+4).

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
