Question

Write the equation of the line parallel to the line 4x + 2y = 5 and passing through the point (-3,5).

2y/2 -4x/2 +5/2
m=2

y=-4x+20 ?

Answer 1

Answer 2

4x + 2y = 5
i think your slope is wrong... subtract 4x on both sides:
2y = -4x + 5
divide everything by 2:
y = -2x+5

so your slope is m=-2, for a parallel line. Now use point-slope form again, y-y1 = m(x-x1) with the point (-3,5)

Answer 3

y-5=-2x+6
then -5 on both sides
y=-2x+1

Answer 4

very good! but i think you missed a negative...

y-5 = -2(x-(-3))

Answer 5

oh yeah lol, y=-2x-1

Answer 6

:D

Answer 7

I have on now with perpendicular, would I do the same steps?

Answer 8

basically BUT remember you have to get the negative reciprocal of the original line's slope.
