y=1/2x - 2

Step-by-step explanation:

The y-intercept is -2 and the slope of the line is 1/2. You can find the slope by using the rise over run method, which is the change in y over the change in x. In the points, x changed by +2, and y by +1, which is 1/2. Substitute that into the formula y=mx + b using one of the points to find the y-intercept, or b. You could use -4 = 1/2(-4) + b, solve for b, and you would get -2.

(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
