Answer:

y = -1/4x -1

Step-by-step explanation:

Mathematically, we have the slope intercept form as;

y = mx + b

where m is the slope and b is the y-intercept

from the question;

m is -1/4

So we have :

y = -1/4x + b

To get the value of b, we substitute the coordinates given and solve for b

Firstly, multiply through by 4

That will

give ;

4y = -x + 4b

4(-4) = -12 + 4b

-16 = -12 + 4b

-16 + 12 = 4b

4b = -4

b = -4/4

b = -1

So the equation in the slope intercept form is;

y = -1/4x -1

Write -12x+16y=-16 in intercept form
valkas [14]

Slope intercept form - y = mx + b

Steps:

First: Add 12 to both sides

Second: Divide 16 on both sides

Third: Simplify if needed

Fourth: Make sure its in the form of y = mx + b

                               

-12x + 16y = -16

+ 12             + 12

16y = 12x - 16

/16     /16   /16

y = 12/16 x - 1

12/4 = 3

16/4 = 4

Answer - y = 3/4x - 1

Hope this Helps!!

What is the sum of the measures of the exterior angles of a nonagon?
olchik [2.2K]

For this case we have by definition, that the sum of the exterior angles of a polygon is equal to 360 degrees, only when considering only one exterior angle for each vertex of the polygon, regardless of the number of sides it possesses. That said we have to:

The external angle of a regular polygon is given by:

\frac {360} {n}

Where:

n: It is the number of sides of the polygon

Then, for a nonagon each exterior angle will measure:

\frac {360} {9} = 40 degrees

Answer:

40 degrees each exterior angle

360 degrees the sum
