(-9,7), (6,2) write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form

y = (2 - 7) / (6 - (-9)) * (x - (-9)) + 7

y = -5 / (6 + 9) * (x + 9) + 7

y = -5 / 15 * (x + 9) + 7

y = -1/3 * (x + 9) + 7

y = -1/3 * x - 3 + 7

y = -1/3 * x + 4

answer: the first graph

step-by-step explanation:

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.
