4.) F(-2,-2) G(4,-4) H(2,6)
Hope this helps!!
Answer:(-3 , -15)
X= -3 and Y= -15
-2 is the only domain I think. The rest are not. Hope I’ve helped.
Step-by-step explanation:
With the given points, we can first find the gradient of the line:
gradient = (2+1)/(-4-8)
= -1/4
We also know that the formula of a straight line is
Y = mX+C, where m is gradient and C is y intercept.
Hence by substituting the coordinates (-4, 2) and the gradient -1/4, we get:
2 = (-1/4)(-4) + C
<u>C = 1</u><u>.</u> Hence, Answer is C.
(Actually, you can just draw a straight line connecting the 2 coordinates and find out the y intercept)
The answer is A=81. You multiply 9 x 9 and then you get 81. Since all sides on a square are equal, you multiply the side length by itself to get the area. Hope that helps! Have a great day!
