Question

The pair of linear equations are:

$y=3x-1$
$y=3x+2$

• A. Perpendicular
• B. Parallel
• C. Intersecting but not at right angles.
• D. Overlapping

Answer 1

Answer: (B)

Given equations are $y=3x-1$ and $y=3x+2$

Let's find the pair of values of $(x,y)$ to plot a graph

$x$	$y=3x-1$	$y=3x+2$
$-5$	$-16$	$-13$
$-1$	$-4$	$-1$
$2$	$5$	$8$
$5$	$14$	$17$

Plot the points on the graph and we get the above image.

Clearly from the above graph, the lines are parallel to each other.

Hence, option B is correct.
