What is the equation of the line that passes through the point (15,9) and (-2,9)

since they have the same y value, your equation is just y=9

I hope this helps!

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!
