Question

Which ordered pairs in the form (x, y) are solutions to the equation 3x−4y=21?

Select each correct answer.


(−3, 3)

(11, 3)

(−1, −6)

(7, 0)

Answer 1

Step-by-step explanation:

$3x - 4y = 21$

$- 4y = - 3x + 21$

$\frac{ - 4y}{ - 4} = \frac{ - 3x}{ - 4} + \frac{21}{ - 4}$

$y = \frac{3}{4} x - \frac{21}{4}$
