Question

FAN AND MEDAL
is (4, 35) a solution of y < 5x + 8

Answer 1

(4,35) refers to the fact that x = 4, y = 35

Answer 2

so it is?

Answer 3

so replace x with 4 and y with 35 to get...

y < 5x + 8

35 < 5*4 + 8

35 < 20 + 8

35 < 28

is that last inequality true? or is it false?

Answer 4

false

Answer 5

so y < 5x + 8 is false when x = 4, y = 35

Answer 6

meaning that (4,35) is NOT in the solution set (shaded solution region)
