Question

A line passing through a point a(3,0) makes 45degree angle with the positive direction of x axis

Answer 1

Answer:

Step-by-step explanation:

Slope(m)=tan 45°

=1

The given point is a(3,0)

Therefore x=3 & y=0

As we know y= mx + c

Putting the value of x and y and m in this formulae

y= mx + c

Or 0= 1*3 + c

Or c= -3

Now the equation of the line is

y= 1*x + (-3)

Or y= x - 3

Or x - y - 3 =0
