Answer:
The equation of straight line is 3 x-y-5=0
Step-by-step explanation:
The equation of straight line having slope m = 3 and passing through the point (2,1) is
the standard form of straight line is [tex]y-y_{1} = m (x-x_{1} )[/tex]
now substitute m = 3 and point (2,1) is
[tex]y- 1 = 3(x-2)[/tex]
[tex]y - 1 = 3 x - 6[/tex]
[tex]3 x-y -6+1=0[/tex]
[tex]3 x-y -5 =0[/tex]
The equation of straight line is 3 x-y-5=0
