Question 82957
Since the unknown line is parallel to {{{y=(5/2)x+6}}} we know the slope of this line (of both lines actually) is {{{5/2}}}. So we know the slope is {{{5/2}}} and the line goes through (2,1), so lets find the equation:


*[invoke find_line_by_slope_and_point 2, 1, 2.5]


or in other words, the equation is


{{{y=(5/2)x-4}}}
