For this case, we must write the equation of a line in a standard way. Which is given by: y = mx + b. Where "m" is the slope and "b" is the cut point with the y axis. The slope is given by:
[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}[/tex]
To find the slope, substitute two points[tex](x_ {1}, y_ {1})\ and\ (x_ {2}, y_ {2})[/tex]through which the line passes.
In this case, we were given the cut point [tex]b = 3[/tex], so we have the following equation:
[tex]y = mx + 3[/tex]
Answer:
[tex]y = mx + 3[/tex]
