Question 1091946
If I plot {{{W}}} on the vertical axis and
{{{M}}} on the horizintal axis,
I am given the point ( 676,527 )
The slope is [ change in W ] / [ change in M ]
{{{ m = 61.9/100 }}}
{{{ m = .619 }}}
Use the general point-slope formula
{{{ ( W - 527 ) / ( M - 676 ) = .619 }}}
{{{ W - 527 = .619*( M - 676 ) }}}
{{{ W - 527 = .619M - 418.444 }}}
{{{ W = .619M + 108.556 }}}
--------------------------
The answer is (3)
check:
does the line go through ( 676,527 )
{{{ 527 = .619*676 + 108.556 }}}
{{{ 527 = 418.444 + 108.556 }}}
{{{ 527 = 527 }}}
OK
