Slope intercept formula ; " y=mx+b" "b" = y intercept , "m" = slope
Your line equation is " y= x-3" so the slope would be the coefficient next to the x. Since there is no coefficient next to the x , the slope would be 1 because one times x would equal x) .
The area for a circle with a diameter of 8 cm is 50.24 cm². The area of a circle with a radius of 3 cm is 28.26 cm². 50.24 - 28.26 = 21.98 cm. So the difference is 21.98 cm.
