First we find the slope of the line AB passing through the point (2,0)

line AB is perpendicular to the line , this equation is slope intercept for, which is so our m or slope is

Since the slope of line AB is perpendicular to then we use the equation , so what do we multiply by to get -1? -4 right, so that's the slope of line AB with the point (2,0)

Now line CD is parallel to line AB, that means it has the same slope as AB, so slope of CD is -4

So we make the equation so m= -4 and our point is (-1,6)

thats the equation of line side CD

Answer:


y=-4x+2

Explanation:

  • First we find the slope of the line AB passing through the point (2,0)
  • line AB is perpendicular to the line
    y=(1)/(4)x-3 , this equation is slope intercept for, which is
    y=mx+b so our m or slope is
    (1)/(4)
  • Since the slope of line AB is perpendicular to
    m=(1)/(4) then we use the equation
    slope of line1* slopeofline2=-1 , so what do we multiply
    (1)/(4) by to get -1? -4 right, so that's the slope of line AB with the point (2,0)
  • Now line CD is parallel to line AB, that means it has the same slope as AB, so slope of CD is -4
  • So we make the equation
    y-y_1=m(x-x_1) so m= -4 and our point is (-1,6)

  • y-(6)=-4(x-(-1)\\y-6=-4x-4\\y=-4x-4+6\\y=-4x+2 thats the equation of line side CD
