Question

Is there anything which can convert a graphical drawing to mathematical equation?​

Answer 1

Answer:

Divide the difference in y-coordinates by the difference in x-coordinates -- 6 ÷ -3 = -2. This is the line's gradient. Insert the line's gradient and the y-coordinate from Step 1 as "m" and "c" in the equation "y = mx + c." With this example, that gives -- y = -2x + 8.
