suppose you are given a line described by the equation y=50-4x and you are told that the x value has increased by 10 units at every y value. What is the equation for the new line
hi
tha value of x has incresed by 10 at every y....
means the line has translated on positive x direction by 10 units....
hence just write (x-10) in place of x....
that's all....
priviously y=50-4x
now y=50-4(x-10)
y=90-4x
