The coordinate grid shows points A through K. Which points are solutions to the system of inequalities listed below?

2x + y ≤ 10
2x − 4y < 8

A.) A, C, D, K
B.) E, F, G, J
C.) A, C, D, H, K
D.) E, F, G, H, J

Answer 1

substitute each points and see iif they will fit

Answer 2

do you see where point A is?

Answer 3

@celinegirl do you see where point A is?

Answer 4

the x axis is the horizontal axis

Answer 5

the point A is over -5 on the x axis

so x = -5

Answer 6

the y axis is vertical

so y = 4

Answer 7

now we turn to the first inequality 2x + y ≤ 10

Answer 8

2x + y ≤ 10

2(-5) + 4 ≤ 10 ... replace x with -5 and y with 4

-10 + 4 ≤ 10

-6 ≤ 10 ... this inequality is true, so (-5, 4) is a solution to 2x + y ≤ 10

Answer 9

making sense?
