Select all of the ordered pairs that satisfy the function y=−4/3x+4.

Question

1. (–6, 12)
2. (–4, 4)
3. (15, –16)
4. (6, –4)

Answer 1

12 = (4/3)(-6) + 4 = 8+4 = 12

first point (-6,12) satisfies the function

just plug in the values, x=-6 and y=12

4=(4/3)(4)+ 4 = 16/3 + 12/3 = 28/3 = 9 1/3

(-4,4) doesn't work

-16= (4/3)(15) +4 = 20+4 = 24

doesn't work, it would have worked had the point been (-15,-16)

-4=(4/3)(6)+4 =12

last one doesn't work, but it would have worked had the point been (-6,-4)

Just the 1st point satisfies the function, (-6,12)

this all assumes the equation was y=(4/3)x + 4, and not y=4/(3x) + 4

the way it's written would be the latter, but that's unlikely as the intent, as also none

of the points would then satisfy the equation
