Question 825334
What is the importance of the right-hand point?


Two points given, line equation containing these points wanted.
{{{y=mx+b}}}, slope-intercept form.
{{{m=(5-1)/(2-0)=2}}}.
From slope-intercept form, {{{b=y-mx}}}.  Use either given point:
{{{b=1-2*0}}}
 {{{b=1}}};
Equation is {{{highlight(y=2x+1)}}}
