Question 779622
Use the fact that slope = ( change in y ) / ( change in x )
given the points (4,5) and (6,6),
slope = {{{ ( 6 - 5 ) / ( 6 - 4 ) }}}
slope = {{{ 1/2 }}}
--------------------
The general form of a straight line is:
{{{ y = m*x + b }}}
where {{{ m }}} = slope and
{{{ b }}} = y intercept
So far I have,
{{{ y = (1/2)*x + b }}}
I also know the line goes through (0,0)
so, I can say:
{{{ 0 = (1/2)*0 + b }}}
{{{ b = 0 }}}
The line is {{{ y = (1/2)*x }}}
