These are both equations of a straight line.

Explanation:

These are both equations of a straight line.

They both have: an x-term, a y-term and a number term.

To be able to compare their slopes, change the equations into slope-intercept form: #y = mx + c#

#y = 2x +4 and y = -2x +5#

The lines are not parallel because the slopes are different.
The lines are not perpendicular. #2xx-2 = -4#
For them to be perpendicular, #m_1 xxm_2 = -1#
