Question 918705
Compute the slope.
{{{(4-(-4))/(1-(-1))=8/2=4}}}


Solve the slope-intercept form equation for b.
{{{y=mx+b}}}
{{{b=y-mx}}}


Pick either of the points to be contained on the line and evaluate b.
Using (1,4),
{{{b=4-4*1}}}
{{{b=0}}}


Form the slope-intercept equation for this line.
{{{highlight(y=4x)}}}



--
b=0 so not needed to be shown in the resulting equation.
