Write it in y= mx+b form. Subtract 5x from both sides to get 4y = -5x + 100. Divide by 4 so the answer would be y= -5/4x + 25.
-9 to 0 is 9 and 0 to 14 is 14.
Total distance = 9 +14 = 23
I don't know the answer but try using PEMDAS. (Parentheses, Exponents, Multiplication, Division, Addition, and then Subtraction)
-5
a^2-25=0
a^2=25
take the square root of both sides
a=5, and -5
