Final answer:
The given lines represented by the equations y = 4x + 12 and y = (-1/4)x + 8 are perpendicular to each other as their slopes are negative reciprocals.
Step-by-step explanation:
We need to determine if the lines represented by the equations y = 4x + 12 and x + 4y = 32 are parallel, perpendicular, intersecting, or coinciding. To do this, we should first express the second equation in slope-intercept form, just like the first one, which is y = mx + b where m is the slope and b is the y-intercept.
Rewriting the second equation, we get:
- x + 4y = 32
- 4y = -x + 32
- y = (-1/4)x + 8
The line represented by y = 4x + 12 has a slope of 4, and the line represented by y = (-1/4)x + 8 has a slope of -1/4. Since the slopes are negative reciprocals of each other, the lines are perpendicular and they intersect at a 90 degree angle.
