Question

Choose the equation of the line passing through the point (2, 6) and parallel to y = -3x - 4.

y = 3x - 12

y = -3x

y = -3x + 12

y = 3x

Answer 1

easy,
y= -3x + B
Than just plaggin the given point:)

Answer 2

y= -3x +B
6 = -3(2)+B
6= -6 +B
B= 12

y=-3x +12

Answer 3

again, use the
(y-y1)=m(x-x1)

Answer 4

Yeah, you can also use that formula. However I like the other format is very simple. If the slopes are PARALLEL than you keep the slope the same from the original equation and plug in whatever order pair/solution they give you.

If they want Perpendicular than you take the original slope and you take the negative reciprical of it.

Ex. y= -3X
Parallel: y= -3x + B; plug in (x,y) to ge B and rewrite final equation.
Perpendicular: y= 1/3 x + B
