Now you check the first digit to the right of the tens digit. If it is from 5 to 9, the tens digit goes up 1. If it is from 0 to 4, the tens digit remains the same.
In this case, the digit to the right of the tens digit is 2. Since 2 is from 0 to 4, the 9 remains as is and does not go up by 1.
First convert the equation to y=mx+b form you’ll get y=5/6x+27 then to find the line perpendicular to this equation, you have the flip the slope. ending with -6/5
