The main formula of a line is;
y=mx+n
We should use one point to find the real equation. If we use (10,-9) point;
y = m x + n - 9 = 10 m + n
a is the slope of the equation, we found that as −2;
- 9 = ( 10 - 2 ) + n - 9 = - 20 + n n = 11
So the equation of the line will be;
y = m x + n y = - 2 x + 11 ̲
