Which point on the line 5x + y = 26 is obtained by taking y = 1?
Answer and explanation
Correct answer: (5, 1)
Substituting y = 1 in 5x + y = 26 gives 5x + 1 = 26, so 5x = 25 and x = 5. Therefore, the ordered pair is (5, 1). In option B, the x- and y-coordinates are interchanged. As an exam tip, verify a point by substituting both coordinates into the original equation.
