Quadrant II

The coordinate plane is formed by the intersection of a vertical and a horizontal number line. What is the horizontal number line called?

Given an ordered pair, (x,y), the first number is the x coordinate.

The second number in an ordered pair (x,y) is the y-coordinate for that point.

3x - y = 4

Get y by itself to see if it is the same as y = 3x - 4:

3x = 4 + y

3x - 4 = y

Therefore, 3x - y = 4 is the equivalent of y = 3x - 4.

using the t-table determine 3 solutions to this equation: y equals 2x

4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1)

(4x + 2y)(x - 1).

Yes.

Any pair of numbers where the 'y' is 5 more than the 'x'. There are an infinite number of suitable pairs.

2y-2x=10

2y-2x+2x=10+2x

2y=2x+10

divide both side by 2.

y=x+5

23y-11y = 12y

Any graph with the slope of -1/2

Assuming you meant 5x-2y=20...

5x - 2(0) = 20

5x = 20

x = 4

X-intercept is 4

The solution is: x = 1 and y = -1

write equation in standfrd form

y =mx + b where b = y intercept

5x - 2y =20

5x -20 = 2y

5/2 x -10 = y

when x = 0 y = -10, the y intercept

It is the ORDINATE.

The numbers are 55, and 57.

Two consecutive integers have an odd sum.

If you mean: x+y = 1 then yes (0, 1) is a solution and the other is (1, 0) for the points of a straight line equation

Yes, because if you sub in for x and y, you get 4-0=4 and this is true

If Y and y are the same, then it is -y + 4 or 4 - y.

It is the point of origin which is located at (0, 0) on the Cartesian plane
