Question 119821
#1







First convert the standard equation {{{2x-9y=5}}} into slope intercept form


*[invoke converting_linear_equations "standard_to_slope-intercept", 2, -9, 5, 2, 1]




Now let's find the equation of the line that is perpendicular to {{{y=(2/9)x-5/9}}} which goes through (6,-13)


*[invoke equation_parallel_or_perpendicular "perpendicular", "2/9", "-5/9", 6,-13]

#3









First convert the standard equation {{{x+3y=3}}} into slope intercept form


*[invoke converting_linear_equations "standard_to_slope-intercept", 1, 3, 3, 2, 1]




Now let's find the equation of the line that is perpendicular to {{{y=(-1/3)x+1}}} which goes through (6,-1)


*[invoke equation_parallel_or_perpendicular "perpendicular", "-1/3", "1", 6,-1]
