GB-23-06-001 · Parallel lines
Show that the lines and are parallel.
Coordinate Geometry: Parallel Lines
Booklet p. 79 & p. 82
Method
1) Rearrange both equations into y = mx + c form
2) Compare gradients: parallel lines have equal gradients m
Worked Example (GB-23-06-001)
1)
Divide the second equation by 2.
2)
Both gradients are 5, with different intercepts.
Ans =
Both have gradient 5.
