If someone could answer these two questions, that would be wonderful:

1. describe how an ordered pair represents a point on a coordinate plane. include the terms x-coordinate, y-coordinate, and origin in your answer.

2. give the coordinates of one point in each of the four quadrants, one point on the x-axis, and one point on the y-axis

1. An ordered pair is a pair of numbers in parentheses, separated by a comma, which indicates the distance of a point from the origin. The first number represents the x-coordinate (where it is from side-to-side), and the second number represents the y-coordinate (where it is from up and down).

2. The four quadrants of the basic plane are listed in this order:

  II    |     I
        |   

        |
 III    |    IV

A point in the first quadrant (I) could be (5, 10), since that means that you would be moving right 5 and up 10.

A point in the second quadrant (II) could be (-3, 6), since that means that you would be moving left 3 and up 6.

A point in the third quadrant (III) could be (-7, -1) since that means that you would be moving left 7 and down 1.

A point in the fourth quadrant (IV) could be (2, -6) since that means that you would be moving right 2 and down 6.

A point on the x-axis could be (9, 0) since that means that we are moving right 9 and making no vertical movement.

A point on the y-axis could be (0, 4), since that means that we are going up 4 and making no horizontal movement.

Hope that helped! =)

121 pints. they had 176 and drank 55

and y≤ -x +4 .

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

.

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

y≤ -x +4 .
