Rewrite each equation in slope-intercept form, if necessary. Then determine whether the lines are parallel Explain 2x+ 5y = 15
6x + 2y = 4
Are the lines parallel?
A. No, since the product of the slopes of the lines is - 1, the lines are perpendicular.
B. Yes, since both lines have a slope of -2/5
the lines are parallel
C. Yes since both lines have a slope of - 3, the lines are parallel
D. No, the slope of the first line is - and the slope of the second line is -3. Since the slopes are not equal, the lines are not parallel.
