Answer:

[tex]y - 2x - 1 = 0[/tex]

Step-by-step explanation:

the slope is :

[tex] \tan( \alpha ) = 4 \div 2 = 2[/tex]

at a pt on graph , when

[tex]x = 1 \\ y = 3 \\ [/tex]

therefore, coordinates are (1,3)

The equation is :

[tex](y - 3) = slope \times (x - 1) \\ (y - 3) = 2 \times (x - 1) \\ y - 3 = 2x - 2 \\ y - 2x - 1 = 0[/tex]
