Question

How do you write an equation in slope-intercept form for this problem?!
(0,0); y=-3x+2

Answer 1

This is already in slope intercept from >.<

Answer 2

yea as fizi said, y = mx + b :) cheers

Answer 3

already in the form

Answer 4

@tHe_FiZiCx99
I realized that too but in my book it says "write an equation in slope-intercept form of the line that passes through the given point and is perpendicular to the graph of the given equation." So I think it means I need to substitute the x and y values but their both 0

Answer 5

Ohh ^^ well what're the "given points"

and its perpendicular so its the reciprocal, so suppose 3/4x I'd be -4/3x

Answer 6

So would it be y=-1/3x+2 ?

Answer 7

what're the given points it says it gives you.

You would plug in y - y1=m(x-x1)

Answer 8

The given points are (0,0)

Answer 9

Did I write the answer right?
y=-1/3x

Answer 10

For example suppose it says, find the equation that is perpendicular to y = 3/4x + 6 and the given points are (-8,6)

So the perp if 3/4 is -4/3x

So, to find the equation with the new given points plug them into, y - y1=m(x-x1)

So, y-6=-4/3(x-(-8))

-4/3 * 8/1 --> -4 * 8 = -32/3

Y-6 = -4/3x - 10.6
+6 +6

y = -4/3x -4.6
