What is the intersection for these two slopes?

x = - 5 / 9
50 / 9 - 10 y = 6
10y = 50 / 9 - 6
10 y = - 4 / 9
y = - 4 / 90
y = - 2 / 45
x = - 5 / 9 , y = - 2 / 45

these equations represent 2 lines.
To find their intersection I substauted x from the second into the first to find a y value then used the y value. The second equation is a straight vertical line to the left of the y axis and has an infinite slope at 90 degrees so its x coordinate of intersection is its equation (-5/9).
-10x-10y=6 10y = -10x-6 y =[-10x-6] / 10
9x=-5 x= -5/9
y= [-10(-5/9) -6]/10
y= -2/45
your point is (-5/9 , -2/45)

9x = - 5
x = - 5/9
- 10(- 5/9) - 10y = 6
50/9 - 10y = 6
50/9 - 6 = 10/y
50/9 - 54/9 = 10y
- 4/9 = 10y
y = - 2/45
Answer: (- 5/9, - 2/45)

(-5/9,-2/45) substitute x=-5/9 in first equation
