The answer to ur question is 54°
Given:
The two end points of a line are (2,10) and (3,-5).
To find:
The equation of the line in the slope intercept form.
Solution:
The slope intercept form of a line is

Where, m is slope and b is the y-intercept.
The two end points of a line are (2,10) and (3,-5). So, the equation of the line is




On further simplification, we get



Therefore, the slope intercept form of the given line is
.
Yes cause he can decrease the perimeter in any way and it would change the area and idk the other 2 in the front
He sold it for $12 since 20% of 10 is 2
