What is true about the graphs of y = 4x + 6 and y = (1/4)x + 6
A.) They are parallel B.) They have the same slope C.) They are perpendicular D.) They do not intersect E.) They are the same line
Slopeintercept form is y = mx + b
m is the slope b is the yintercept In y = 4x + 6 slope is 4 yintercept is 6 In y = (1/4)x + 6 slope is 1/4 yintercept is 6 Perpendicular lines have slopes which are negative reciprocals. 4 and 1/4 are slopes which are negative reciprocals, therefore the two lines are perpendicular, and they also intersect at the yintercept since it is the same in both equations C.) They are perpendicular
