Drag and drop each pair of lines into the correct category to indicate whether the pair of lines are parallel, perpendicular, or

ANTONII [103]

Answer:

Step-by-step explanation:

(1). $\frac{1}{7}$ x + y = 9 and y = - 7x ( Neither ) ; lines intersect.

(2). y = 3x - 3; 12x - 4y = 12 ( Neither ) ; Lines are overlapped or both equation are of the same line.

(3). 7y = 2x + 1; 14x + 4y = 12 ( Perpendicular ) ; $m_{1}$ = $\frac{2}{7}$ and $m_{2}$ = - $\frac{7}{2}$ , slopes are opposite reciprocals.

(4). x - 4y = 18; y = x + 4 ( Neither ) ; lines intersect.

(5). 3x - 4y = - 1; 3y = - 4x + 5 ( Perpendicular ) ; $m_{1}$ = $\frac{3}{4}$ and $m_{2}$ = - $\frac{4}{3}$ , slopes are opposite reciprocals.
