If the line must be perpendicular to the equation, that means the slope is the reciprocal of the one in the given equation. So first we find that, the slope of the given equation.
- 2y + 4 = 6x + 8 - 2y = 6x + 4
y = - 3x - 2
So the slope of the given equation is - 3x. That means the slope of our perpendicular equation must be 1/3x
Now to find the value of n, plug in our given information and perpendicular slope into the slope equation:
well first you have to multiply like if there was no decimal so 35x49= 1715 then you have to put your decimals in so 3.5 x 4.9= now u put the decimal in it will be 17.15 so there it is.
