Answer:
None.
Step-by-step explanation:
1 - 4 + 121
= -3 + 121
= 118
121 + 1 - 41
= 122 - 41
= 81
141 - 121
= 20
1 - 21 - 1 - 41
= -20 - 1 - 41
= -21 - 41
= -62
None of the expressions have a value of -2.
a) find the slope of the line using the given points.
Slope: 9 - -3/6-0 then slope is 12/6 which is 2
Then using formula: y = mx+b
-3 = 2(0) + b
b = -3
The equation is: y = 2x -3
B. Slope of a perpendicular is -reciprocal of first line. So here the slope will be -1/2
y = mx + b is used again
2 = -1/2(0) + b
b = 2
The equation is: y = -1/2x +2
Answer:
3.25 :)
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
perpendicular lines are the negative reciprocals of each other, and a pair of these lines intersects at 90 degrees.
