The y intercept (b) is where is crosses the y axis = 5
The x intercept is where is crosses the x axis = 4
The slope is rise over run or y2 - y1/x2 - x1
m = 0 - 5/4 - 0
m = -5/4
y = mx +b
y = -5/4x + 5

x=72
The decrease is 25% so this means that 22 is 75% of the original number (100% - 25% = 75%)
Divide 22 by 75%:
22/ 0.75 = 29.3
The answer is 29.3
180 degrees is half of a circle, and clockwise means turning in the direction a clock does - right.
So a point would be turned right halfway around.
