The line y = mx + c has a slope of m.
Parallel line:
A parallel line will also have a slope of m, and should be of the form
y = mx + k
Because the line passes through the point (a,b), therefore
ma + k = b
k = b - ma
The equation of a parallel line is
y = mx + b - ma
= m(x-a) + b
Perpendicular line:
A perpendicular line will have a slope of -1/m, because the product of slopes should be -1.
The equation for a perpendicular line is of the form
y = -(1/m)x + k
Because the line passes through (a,b), therefore
-(1/m)a + k = b
k = b + a/m
The equation for a perpendicular line is
y = -(x/m) + b + a/m
= -(1/m)(x-a) + b
Answer:
Parallel line:
Perpendicular line:

Answer:
7x - 8
Step-by-step explanation:
5x + 2 + 2x - 10
Rearrange terms:
5x + 2x - 10 + 2
Combine like terms (add 2x and 5x):
= 7x - 10 + 2
Combine like terms (add -10 and 2):
= 7x - 8 (This is the simplified form).
Answer:2349.91
Step-by-step explanation:
A=2πrh+2πr2=2·π·11·23+2·π·112≈2349.9113
Answer:
Expand
2b + 3 = 2 -3b -9
Correct like terms
2b + 3 = 3b - 7
Move 2b to the otherside as a negative number and -7 to the otherside positive number.
-4 = -5b
Divide both sides by negative five
b is equal to 4/5
