Question

Please help me!
Is (-2, -6) a solution to the equation y=3x
yes or no?

Answer 1

(-2,-6) is an ordered pair in the form (x,y)

so x = -2 and y = -6

Answer 2

Yes
\[y=3x\]\[-6=3 \times -2\]\[-6=-6\]

Answer 3

Plug those values into the equation to get...

y = 3x

y = 3*(-2) ... replace x with -2 (since x = -2)

-6 = 3*(-2) ... replace y with -6 (since y = -6)

-6 = -6 ... multiply on the right side

Since that last equation is true, this means x = -2 and y = -6 make y = 3x true

So (-2,-6) is indeed a solution (one of infinitely many)
