Rearrange: 2y = 6 -3x
2y = - 3x + 6
y = -1.5x + 3
Now, substitute, perpendicular lines have the same gradient so:
-1 = -1.5 (2) + c
- 1 = -3 + c
2 = c
equation for new line: y = 1.5x + 2
Answer:
12
Step-by-step explanation:
Then the -12 and +12 will cancel out, so you're left with a clean isolated r on the left:
r -12 +12 = 19 + 12
r = 31
21 x 9 = 9 x 21 is the commutative property.
