Which of the following pairs of points both lie on the line whose equation is 3x-y=2?
Explanation
Answer is (2,4) and (3,7)
substituting values of x and y,
\(3 x-y=(3 \times 2)-4=2\)
\(3 x-y=(3 \times 3)-7=2\) satisfy the equation.
Test each pair: Only (2, 4) and (3, 7)
satisfy the equation.
None of the other pairs work.
