Find the equation of a line having incilnation 135 degrees and y intercept 5. This is very urgent please

We know that the equation of a line with slope m and y-intercept c is given by:

y = mx + c

Here, m = 135° = tan (180° - 45°) = - tan 45° = -1

It is given that y-intercept, c= 5

Hence, the required equation of the line is:

y = (-1) x + 5

⇒ x + y = 5
