Given :
A line passing through the point (1, 3) that has a slope of -2.
To Find :
The equation of such line.
Solution :
Let, the equation of line is :
y = mx + c
Here, m is slope i.e m = -2 and c is y-intercept.
So,
y = -2x + c
It is also given that the line passes through (1, 3).
3 = -2× 1 + c
c = 5
Therefore, the equation of line is y = -2x + 5 .
