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 equation is y = -3x.
the function is linear.

The second option and the third option are true.

Step-by-step explanation:

The formula of the line in slope-intercept form is:

Where m is the slope and b is the y-intercept.

By definition, the y-intercept in a direct variation is 0.

Therefore, substituting and into the equation, you obtain:

Then, the equation is:

As this is a line, it is a linear function.

Therefore, the second option and the third option are true.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
