Solve for y.

y-3x=1

y=? x+?

graph the equation.

y=3x+1

Step-by-step explanation:

add 3x to both sides to get it into standard form. since the slope is 3x this means we go up 3 units and to the right 1 unit. since our y-intercept is 1 we start this from their as shown in the pictures above^

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
