For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the y axis
We have according to the data:

Thus, the equation is of the form:

We substitute the given point:

Finally, the equation is:

Answer:

Hellooooo!!!!
My joke is, what has a neck but no head, but can wear a cap?
Have fun! please give brainliest if you could!! <3
Sf=scale/original
sf=14/20
sf=0.7
7/10 / 3/1
7/10 x 1/3
7/30
(not sure if this is correct)
