To find the x-intercept, substitute in 0 0 for y y and solve for x x . To find the y-intercept, substitute in 0 0 for x x and solve for y y . x-intercept(s): ( 5 , 0 ) ( 5 , 0 ) y-intercept(s): ( 0 , − 15 )
400 because divide 60 by 15 in order to get 1% of the unknown number, which is 4. Then, just multiply 4 by 100 to get 100% of the number, which equals 400.
