Question

What is an equation in point slope form for the line perpendicular to y=4x-5 that contains (-10,3)?

Answer 1

if 2 lines r perpendicular to each other and if the slope of one line is "m" then the slop of the other lone is "(-1/m)"

so thw slope of the line u want will be "(-1/4)"

then the basic format will be
y = mx + b
= (-1/4)x + b
then consider the coordinates (-10 , 3) and substitute them in the above equations
3 = (-1/4)10 + b
b = 3 + 10/4
= 22/4
= 11/2

therefor the line u want is
y= (-1/4)x + 11/2

got it :) ?

Answer 2

Yes, thank you so much. Can you help me with one more?

Answer 3

if it is within my limit ... i will

Answer 4

Write the equation for the vertical line that contains point E(6,4).

Answer 5

a vertical line means that the x value of this is always a constant
so the equation is
x = 6

Answer 6

Thank you.
