Question

what do the following two equations represent? please help 4x+2y= 10 4x-2y= -10 a) the same line b) distance parallel lines c) perpendicular lines d) intersecting, but not perpendicular lines

Answer 1

d) intersecting, but not perpendicular lines

Explanation:

Changing the sign of one of the variable terms causes the line to be reflected across one of the axes. The slope is the opposite of what it was. Since the original slope was not 1 or -1, the resulting line is not perpendicular to it. Lines with different slopes will be intersecting.

The two lines are intersecting, but not perpendicular.
