1. Fill in the blank with the appropriate word, phrase or symbol

            a)     The point (2, 7) is located in the ______________ quadrant.

            b)     The point (-3, -5) is located in the ______________ quadrant.

2. Determine which of the ordered pairs satisfy the given equation.

4x- y = 4 , (0,-4), (1,0), (2, -3)

Solution

1)

Q-1 seems incmplete, so i shall simply explain it to you

Let the point be (x,y)

If x = positive, y = positive --> quadrant 1
IF x = negative, y = positive ---> quadrant 2
If x = negatve , y = negative --> quadrant 3
IF x = positive, y = negative --> quadrant 4

---------------------------------------------------------------

2)

4x - y = 4
Plug in (0,-4) :
4(0) - (-4) = 4
0 - (-4) = 4
0 + 4 = 4
4 = 4
TRUE

Plug in (1,0) :
4(1) - 0 = 4
4 - 0 = 4
4 = 4
TRUE

Plug in (2,-3) :
4(2) - (-3) = 4
8 + 3 = 4
11 = 4
FALSE

So, points (0,-4) and (1,0) satisfy
Point (2,-3) does not satisfy
