Equation of line
Let m represents the slope of the line;
m is calculated as thus




By substituting the right values in the formula above;
becomes

Multiply both sides by 





Reorder

Hence, the equation that represents the line is 
What is the rest of the question
A^2 + b^2 = c^2
(500)^2 + (1200)^2 = c^2
1,690,000 = c^2
take the square root of 1,690,000
Answer is 1,300 feet
Step one: correspond x values and y values together
it would be: 3, 12 and 4, 16
Step two: divide
12/3 = 4 and 16/4 = 4
both numbers = 4
scale factor is 4
