Question 169518
okay, we find {{{b}}} thru points (4,2) w/ slope=3.
Via Slope intercept Form;
{{{y=mx+b}}}
{{{2=3(4)+b}}}
{{{b=2-12=-10}}}, y-intercept
Therefore, eqn ---> {{{highlight(y=3x-10)}}}, Answer
We see in the graph:
{{{drawing(300,300,-8,8,-12,8,grid(1),graph(300,300,-8,8,-12,8,3x-10),circle(4,2,.15))}}} -------> see Line passes thru points (4,2)
.
Thank you,
