Question 462640: Solve the following systems of equations and state if any lines are parallel: y = 1x + 5
-7x + 45 = y

y+=+1x+%2B+5
-7x+%2B+45+=+y..or y=-7x+%2B+45+
it is evident that these lines are not parallel; they are written in slope-intercept form and slopes are not identical

y+=+1x+%2B+5...this one has a slope m=1
y=-7x+%2B+45+...this one has a slope m1=-7
