Which of the following ordered pairs represents a solution to the equation below?
y=-3x – 2

 (-2,-8)

Step-by-step explanation:

For these types of questions they are very easy. The first thing to know is the points. For this case, we will start off with (1,0) The x is 1 and the y is 0 so you plug them in the equation. You will then get 0=3(1)-2. Once you simplify that you will get 0=1 which is wrong. For the correct answer, the formula will look like this -8=3(-2)-2 which then simplify to -8=-8 which is true.

a) No. it cannot have 4 acute angles because total sum of all 4 angles = 360 degrees

b) Yes, an obtuse angle has > 90 degrees so a quadrilateral can have angles

100, 100 , 100 and 60 for example.

c) Yes A reflex angle has value between 180 and 360 so you could have a quadrilateral whose angles are 270, 30, 30, 30 for example.

d) No because the sum of any 2 reflex angles is greater that 360 degrees
