12.) y = - 5x + 3
Slope = - 5
The slope of a parallel line will have the same slope as the original line, so
m = - 5
x = 2
y = 0
b = y - mx:
b = 0 - [- 5(2)]
b = - (- 10)
b = 10
Equation of Line:
y = - 5x + 10
¯¯¯¯¯¯¯¯¯¯¯¯
13.) y = - x - 4
m = - 1
x = - 1
y = 4
b = 4 - [- 1(- 1)]
b = 4 - 1
b = 3
Equation of Line:
y = - x + 3
¯¯¯¯¯¯¯¯¯
14.) y = ¼ x + 2
m = ¼
x = 4
y = - 9
b = - 9 - ¼ (4)
b = - 9 - 1
b = - 10
Equation of Line:
y = ¼ x - 10

Given line : y = -5x + 3 ............................................ [1]
a.)
A line parallel to [1] and passin to point(2, 0) is : y = -5(x-2),
OR,
y = -5x + 10 >=======================================< ANSWER
b.)
A line Perpendicular to [1] and having point(2, 0) is : y = (1/5)(x-2),
OR,
y = x/5 - 2/5 = 0.2x - 0.4 >================================< ANSWER
Similarly Solve the Left-overs ..........................
