Question

write the equation of the line which passes through (2,-3) and is perpendicular to y=4x+7 in standard form?

Answer 1

perp. line slope = -4

Answer 2

i need steps

Answer 3

find the y-intercept now.

-3 = 2(-4) + c

c = -3 + 8

c = 5


therefore:

y = 4x + 5

Answer 4

m1 = 4, not -4/7.

Answer 5

m1=4
for pependicular is m1xm2=-1
so m2=-1/4
y+3=-1/4(x-2)
y=-1/4x-7/2

Answer 6

sorry i meant this

Answer 7

4y + x + 10 = 0
