What is the slope of the line represented by y= x+ 9 plz

1 is the slope

Step-by-step explanation:

When the equation of a line is written in the form

y = mx+b,  m is the slope and b is the y intercept

y =x +9

y = 1x+9

1 is the slope and 9 is the y 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

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
