The equation Y-3 = -2(x+5) is written in point-slope form. What is the y-intercept of the line?
A -13
B -7
C 2
D 8

B,-7

Step-by-step explanation:

convert the formualt into slope intercept form by adding the 3 and distributing the -2

then you will get y=-2x-7

in slope intercept the B slot is the y intercept, and in this equation it is -7

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
