2x+8y=20 and 3x+9y=50 Parallel-Perpendicular-Intersecting
Are 2x+8y=20 and 3x+9y=50:
parallel, intersect, or perpendicular
Get Eq. 1 into y = mx + b format:
2x + 8y = 20
8y = -2x + 20
Divide each side by 8
Simplifying, we have:
y = -0.25x + 2.5
Final Answer
Slope = -0.25

Get Eq. 2 into y = mx + b format:
3x + 9y = 50
9y = -3x + 50
Divide each side by 9
Simplifying, we have:
y = -0.33333333333333x + 5.5555555555556
