Question 174110This question is from textbook Basic Algebra
: how do you write equations in slope-intercept form and then how can you tell if each pair of lines is parallel, perpendicular, or neither?
y = -4x + 1 and y = -4x - 5 This question is from textbook Basic Algebra
You can put this solution on YOUR website! they are already in slope intercept form y=mx+b where m is the slope
these have the same slope of -4 so they are parallel lines
to be perpendicular the slopes must be negative inverses of each other such as
4 and -1/4 or 6 and -1/6
