Question

Equation for a line parallel?

Answer 1

i did part one and 2

Part 1: m= 6 - 3/8 - 6 = 3/2 = 1.5



3/2 = m (Slope)

Part 2: Point Slope Formula = y – y1 = m (x – x1)

y - 3 = 3/2 (x - 6)

(y-3) * 2 = 3/2 * 2 * (x-6)

2y - 6 = 3(x-6)

2y-6 = 3x-18

2y-6+6 = 3x-18+6

2y = 3x-12

2y/2 = (3x-12)/2
y = (3/2)x - 6

Part 3: Give an example of an equation for a line parallel to your answer from Part 2
Part 4: Give an example of an equation for a line perpendicular to your answer from Part 2

Answer 2

Hey there... lines having same slopes are PARALLEL lines...
For perpendicular lines, let slope of new line be 'm'...
(slope of new line)*(slope of original line ) = -1
i.e. m*(slope of original line) = -1...

Hope this helps :-)
