Step-by-step explanation: If 1 inch is equivalent to 65 miles, then blank inches is equivalent to 2300 miles. Basically all you have to do is divide 2300/65 to get the number of inches equivalent to 2300 miles.
y= -x-9 because you have to find the negative reciprocal of the slope of the original line and then use the point slope formula y-y1=m(x-x1) to find the perpendicular line
