for this, your A might be (0,5), B (5,5), C (2,2).
parallel means railroad tracks: same slope, different intercepts.
line AB in this case has a slope of 0, intercept (0,5), so y₁=0x+5 or just y₁=5
the line passing through C also has slope 0, but intercept (0,2), so y₂=0x+2 or just y₂=2
2. perpendicular means that the slopes of two lines multiply out to -1. If line AB has, for example, a slope of 2/3, then the line passing through C would have slope -3/2 (negative reciprocal). To make things easier have either point A or B be on the x or y axis

Answer:
She'll need to save at least 10 months to be able to go buy the computer.
Step-by-step explanation:
Let
x ----> the number of months
we know that
The inequality that represent this situation is equal to
solve for x
therefore
The minimum number of months is 10
Answer:
Step-by-step explanation:
69
Answer:
y= -10
Step-by-step explanation:
3(y+2) + 2(y-2)
3y + 6 + 2y -4
-2y -6 -2y -6
y= -10
It's complicated to explain but yeah.
Answer is C, 138°
It's the answer that makes the most sense.
