Question 173752
</pre><font size=4><b>

We find first the y-intercept--->{{{b}}} via Slope_intercept form:{{{y=mx+b}}}
Thru points (4,3) with {{{slope=m=7}}}:
{{{3=7(4)+b}}}
{{{3=28+b}}}------>{{{b=3-28=-25}}}
Therefore, it follows {{{y=mx+b}}}----->{{{y=7x-25}}}
In standard form: transpose to the left & change sings :{{{highlight(-7x+y+25=0)}}}
We'll see the graph:
{{{drawing(400,400,-5,5,-30,10,grid(1),graph(400,400,-5,5,-30,10,7x-25),blue(circle(4,3,.20)))}}}
Thank you,
