Find an equation of the line. Write the equation using function notation.
Through (−5,−9); parallel to 6x+5y=11
Solution
Re-write 6x+5y =11 into the form y=mx + c
5y=-6x+11
y = -6/5 x +11/5
Parallel lines have equal gradient m = -6/5
Hence, the equation of the line would be given by
"{y-(-9) \\above{2pt} x-(-5)}=- {6 \\above{2pt} 5}\\\\\n\n5(y + 9) =-6(x + 5)\\\\\n5y +45 = -6x-30\\\\\n5y +6x = -75 [Answer]"
