Question 1097145
Actually, you are given 2 points on a line, and
since 2 points dfine a line, you can plot the line.
The points are:
( 5, 1.45 )
( 15, 3.45 )
Use the general point-slope formula
{{{ ( y - 1.45 ) / ( x - 5 ) = ( 3.45 - 1.45 ) / ( 15 - 5 ) }}}
{{{ ( y - 1.45 ) / ( x - 5 ) = 2 / 10 }}}
{{{ ( y - 1.45 ) / ( x - 5 ) = 1 / 5 }}}
Multiply both sides by {{{ 5*( x - 5 ) }}}
{{{ 5*( y - 1.45 ) = x - 5 }}}
{{{ 5y - 7.25 = x - 5 }}}
{{{ 5y = x + 2.25 }}}
{{{ y = (1/5)*x + .45 }}}
{{{ y = .2x + .45 }}}
-------------------------------
check:
does it go through ( 5, 1.45 ) ?
{{{ 1.45 = .2*5 + .45 }}}
{{{ 1.45 = 1.45 }}}
OK
check ( 15, 3.45 )
{{{ 3.45 = .2*15 + .45 }}}
{{{ 3.45 = 3.45 }}}
OK
