Find the slope of the line that passes through (9, 4) and (4, 12).

Simplify your answer and write it as a proper fraction, improper fraction, or integer.

Answer as a proper fraction is 8/-5;

As an improper fraction is - 1 3/5;

As an integer, we will approximate the slope value from -1.6 to -2

Step-by-step explanation:

Given the points (9,4) and (4,12), find the slope:

Slope= change in y/ change in x.

y2 - y1/x2 - x1

Step 1: Locate the coordinates points:

x1= 9, x2= 4

y1=4, y2= 12

Step 2:Insert the values into the formula Slope =12-4/4-9

=8/-5

Answer as a proper fraction is 8/-5

As an improper fraction is - 1 3/5

As an integer, we will approximate the slope value from -1.6 to -2.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

(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
