CAN I PLEASE GET SOME HELP The function f(x) is graphed on the coordinate plane.

What is f(−4)?

f(-4) = 4

Step-by-step explanation:

Let the equation of the function is,

f(x) = mx + b

where m = slope of the line

b = y-intercept of the line

From the graph attached,

Slope = =

Slope 'm' =

y-intercept 'b' = 2

Therefore, function will be,

f(x) =

For x = -4,

f(-4) =

      = 2 + 2

      = 4

Which is true from the graph.

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.
