Answer:
D.) (-10, 0)
Step-by-step explanation:
(Important:) When you are looking at coordinate points, remember that inside the parenthesis the number on the left (-10 in this case) is the x-coordinate, and the number on the right (0 in this case) is the y-coordinate.
The reason why point D.) is the correct answer, is because when you have your y-coordinate at 0, it must touch the bottom of the y-axis (or line) in order for it to be on the x-axis. But remember that this specific rule only applies now because the y-coordinate is 0. The letter A.) may look correct because it has a 0, but upon placing it on a graph, we notice that it is on the y-axis and not the x-axis.
I have added an attachment of the graph with all points plotted.
I hope that this helps.
Answer:
X = 2 and Y = -3
Step-by-step explanation:
2x+5y=-11 - equation 1
10x+3y=11 - equation 2
from equation 1, 2X = -11 - 5y
X = -11/2 - 5Y/2
X = -5.5 - 2.5Y
insert X = -5.5 - 2.5Y into equation 2
therefore, 10x+3y=11
10(-5.5 - 2.5Y) + 3y = 11
-55 -25Y +3Y = 11
-22Y = 11+55
Y = -66/22
Y = -3
insert Y = -3 into equation 1
thus 2x + 5(-3) = -11
2x - 15 = -11
2x = -11 + 15
2x = 4
x = 4/2
x = 2
ordered pair: X = 2 and Y = -3
