The slope of the graph of a direct variation function is -3. Which of the following is true?

The equation of the function is y = -1/3 x.
The point (2, -6) is on the graph of the function.
The equation is y = -3x.
The function is linear.

The equation is y = -3x.

The function is linear.

The point (2, -6) is on the graph of the function.

Step-by-step explanation:

The function is linear.

direct variation function is always linear. and linear means a straight line which is true in this case

The equation is y = -3x.

equation of line is y=mx+c

where, m=slope= -3.

it is linear so we are assuming it passes origin, (0,0).

m=(y2-y1)/(x2-x1)

now substituting m=-3 and (0,0) in x1 and y1.

-3=(y2-0)/(x2-0)

-3=y2/x2

y2=-3*x2

where y2=y, x2=x,

therefore,

y=-3x.

The point (2, -6) is on the graph of the function.

now,

y=-3x

substituting x=2,

y=-3(2)

y=-6

therefore,

if x=2, y=-6, (2,-6)

because its not ur topic and its not for is for homework not that.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
