The graphs of two linear equations, x + 2y = 15 and 4x + 8y = 13 will be:
A.coincident
B.parallel✓ Correct
C.intersecting at one point
D.intersecting at two points
Explanation
Comparing the two equations: ratios of coefficients are 1/4 = 2/8 = 1/2 but 15/13 ≠ 1/2. Since a1/a2 = b1/b2 ≠ c1/c2, the lines are parallel and have no solution.
