Class 10 Mathematics Pair of Linear Equations in Two Variables Graphical method of finding solutions.ExpertLevel 53

For which value will the lines (4x+ay=16) and (8x+10y=35) be distinct and parallel?

Answer and explanation

Correct answer: (a=5)

For parallel lines, (\frac{4}{8}=\frac{a}{10}), so (a=5). Since (\frac{16}{35}\neq\frac{1}{2}), they will not be coincident.
