Find the x- and y-intercepts of the graph of the equation. f(x) = 4x – 12
x-intercept
(x, y) =
y-intercept
(x, y) =

x intercept is (3, 0).  y intercept is (0, -12).

Step-by-step explanation:

x intercept is when y = 0.  [f(x) = y]  So 0 = 4x - 12. Solving for x gives you a value of 3.  [12 = 4x; divide by 4]

y intercept is when x = 0.  So y = 4(0) - 12.  Solving for y gives you a value of  -12.  [y= 0 - 12; y = -12]

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
