Given:
A line which is passing through (–2, 3), the angle is 45°
By using the formula,
The equation of line is [y – y1 = m(x – x1)]
Here, angle, θ = 45°
The slope of the line, m = tan θ
m = tan 45°
= 1
The line passing through (x1, y1) = (–2, 3)
The required equation of line is y – y1 = m(x – x1)
Now, substitute the values, we get
y – 3 = 1(x – (– 2))
y – 3 = x + 2
x – y + 5 = 0
The equation of line is x – y + 5 = 0
