What is the correct description of the graph of the equations (4x+15y=53) and (9x+31y=110)?

Answer and explanation

Correct answer: Lines intersecting at one point

The coefficient ratios are unequal: \\(\frac{4}{9} \ne \frac{15}{31}\\). Equivalently, the determinant is \\(4\times31-9\times15=-11\ne0\\), so the two lines intersect at exactly one point and the pair has a unique solution. Coincident or distinct parallel lines require the relevant coefficient ratios to be equal. Exam tip: if \\(\frac{a_1}{a_2}\ne\frac{b_1}{b_2}\\), the lines intersect at one point.
