Simply check each answer choice

jim_thompson5910 · Answer

So let's check answer choice A)

2x - 10y = -14

2(-1/2) - 10(1) = -14

-2/2 - 10 = -14

-1 - 10 = -14

-11 = -14

which is false

So (-1/2, 1) does NOT lie on the line 2x-10y = -14

So choice A is NOT the answer

go through the rest of the answer choices and check them

keep in mind that the ordered pair must work for BOTH equations
