Question

write the equation of the line that passes through (1,3) and has a slope of 2 in point slope from

Answer 1

Answer:

The answer is $y=2x+1$

Step-by-step explanation:

                          Slope point form of a line :

Equation of line having slope $m$, which passes through the point $(x_1,y_1)$ is

                                 $\boxed{y-y_1=m(x-x_1)}$

Therefore equation of line through (1,3) with slope 2 is

                                      $y-3=2(x-1)$

                                     $\Rightarrow y-3=2x-2\\\Rightarrow y=2x-2+3\\\Rightarrow y=2x+1$
