What is the slope of the line given by the equation y = -3x?

a. -one third
b. -3
c. one third
d. 3

The correct option is B.

Step-by-step explanation:

The given equation is

          .... (1)

The slope intercept form of a line is

       .... (2)

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

From (1) and (2), we get

The slope of the line is -3.

Therefore the correct option is B.

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
