Answer:
lines b and c are perpendicular
Step-by-step explanation:
Use slope
slope for parallel is the same
slope for perpendicular is negative reciprocal
line a slope- 1-3/-2-0 is -2/-2 or 1
line b slope- 1-4/4-6 is -3/-2 or 3/2
line c slope- 3-1/1-4 is 2/-3 or - 2/3
none are the same so none are parallel
- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular
-10= 7X - 42
-10 + 42 = 7X
32 = 7X
X = 32/7
X = 4.57
Answer:
y = x -2
Step-by-step explanation:
Slope is 1, y-intercept is (0,-2)
