Question 785318
If the value of {{{y}}} changes by {{{15}}} units when the value of {{{x}}} changes by {{{1}}},
  then the slope of that line is   {{{15/1=15}}}

and if line goes through ({{{23}}},{{{-5.1}}}), then equation will be:


*[invoke find_line_by_slope_and_point 23, -5.1, 15]


since you cannot see a line on a graph above, here is another graph: 


{{{ graph(600, 600, -400, 400, -400, 400, 15x-350.1) }}}
