Rotation 90° translates (x, y) to (-y, x). Thus (3, 2) gets translated to (-2, 3). Your green box gets filled with -2.
When you are given a point (x1,y1) and slope m the equation is
y-y1=m(x-x1)
given
slope=7
(x,y)
(3,22)
x1=3
y1=22
y-22=7(x-3) is the equation or
y=7x+1
Step-by-step explanation:
because 9+14+10+7=40, you could say 9/40 or if you wanted to get a percent, you could multiply 40×2.5 ( because 40×2.5=100) then multiply 9×2.5 to get the percent
