Let  the points are

. \ \

Slope of AB = .

Division by zero is undefined,the slope of vertical line is undefined. \ \

So the vertical line AB is .

Slope of BC .

Point - slope form : .

Substitute the values of slope(m) = - 1/2 and on Point - slope form.

.

The line equation of BC is . \ \

Slope of CA .

Point - slope form : .

Substitute the values of slope(m) = 5/2 and on Point - slope form.

.

The line equation of CA is .

Therefore the three equations of the triangle is , and \ \ .
