Answer:
y= -1/3x+9.2
Step-by-step explanation:
I believe that it is 9.2 although it could be another number in the 9's.
The slope is (rise) -1 and (run) 3 and the line crosses the y-intercept at what it looks like 9.2
Yintercept is the point where the line crosses the y axis and where x=0
(x,y)
yintercept at y=b is
(0,b)
Equal in what? Cm, m, mm ?
Take the first point (2, 4) a scale factor of 3/2 will move the x coordinate 2 to 2*3/2 = 3 and the y coordinate 4 will be moved to 4*3/2 = 6.
So the image of ( 2, 4) will be ( 3, 6) TH other verices will move in the same fashion.
