Write the equation of a line in slope intercept form that has a slope of -2 and passes through the point (5,11).

y = -2x + 21

Step-by-step explanation:

use point intercept form: y = mx + b where m is the slope and b is the y intercept

to find the y intercept, b, plug in values into equation and solve for b

11 = (-2) (5) + b

b = 21

then plug into the equation the slope and intercept!

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
