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

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

**Slope-intercept form is y = mx + b**

**m is the slope**

**b is the y-intercept**

__In y = -4x + 6__slope is -4

y-intercept is 6

**In y = (1/4)x + 6**slope is 1/4

y-intercept 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 y-intercept since it is the same in

both equations

**C.) They are perpendicular**
