Question

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, c, d, k e, f, g, j a, c, d, h, k e, f, g, h, j

Answer 1

C

Explanation:

A,C,D, and K

Answer 2

2x + y ≤ 10

y ≤ - 2x + 10 → you can see the line in red

As the sign is ≤, you keep only the part below the red line, included the red line


2x - 4y < 8

- 4y < - 2x + 8

y > (- 2x + 8)/- 4

y > - (1/2)x - 2 → you can see the line in blue

As the sign is >, you keep only the part above the blue line

A, C, D, K
