Answer:
D) y=-4x+2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2-6)/(1-(-1))
m=-8/(1+1)
m=-8/2
m=-4
y-y1=m(x-x1)
y-6=-4(x-(-1))
y-6=-4(x+1)
y=-4x-4+6
y=-4x+2
I believe the answer is 5. Hope this was right for you.

Step-by-step explanation:
The area of the whole rectangle is 91cm. Subtract 2 because of what is not shaded in the bottom right, then subtract 12 from what is not shaded in the top left. That leaves you with 77cm of shaded area.
Answer: " y = 30° " .
_____________________________________
<u>Note</u>: The sum total of the measure of all angles lying on a straight
line is 180°.
So; x + y + z = 180 .
Given: x = 2y ;
z = 3y ;
__________________
Find the value of: " y " ;
_______________________
Since: x + y + z = 180 ;
Substitute: "2y" for "x" ;
and: "3y" for "z" ;
_______________________
2y + y + 3y = 180 ;
6y = 180 ;
______________________
Divide EACH SIDE of the equation by "6" ; to isolate "y" on one side of the equation; and to solve for "y" ;
___________________________
6y/ 6 = 180 / 6 ;
y = 30 ;
____________________________
Let us check our work;
____________________________
2y + y + 3y = 180 ;
Substitute our solved value: "30" ; for "y" ; in the equation; to see if the equation holds true:
____________________________
2(30) + 30 + 3(30) =? 180 ?
____________________________
60 + 30 + 90 = ? 180 ?
____________________________
90 + 90 = ? 180 ? Yes!
