If laser eye surgery is modeled on a coordinate grid.
The laser is positioned at the y-intercept so that the light shifts down 1mm for each 40 mm it shifts to the right.
The light reaches the center of the cornea of the eye at (125,0).
Write the equation of the light beam.
:
the slope will be , find the y intercept (b)
(125) + b = 0
-3.125 + b = 0
b = +3.125
then
y = x + 3.125, is the equation
looks like this
