1. Activity 1
Substitute each pair of coordinates to the
system of inequality below and tell whether
it is a Solution or Not Solution
2x + 5y < 10
3x - 4y = -8

a. (3,5)
b. (-2,-10)
c. (5, -12)
d. (-6, -8)
e. (0,0)​

solution e. (0,0)b. (-2,-10)c. (5, -12)of

2x + 5y < 10

bull

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
