3x = -30
x = -10
Answer:
Equation of line in slope-intercept form is given as y = mx + c, where m is the slope and c is the y-intercept.
Parallel lines have the same slope so slope of line is -2/3x.
Equation of line is y = -2/3x + c.
Substitute (6,-11) into the equation to find c.
-11 = -2/3(6) + c
c = -7
Hence, equation of line is y = -2/3x - 7.

Step-by-step explanation:
The lines are parallel so angels 1,4,5,8 are the same.
Same with angels 2,3,6,7.
To find angels 7 and 2 subtract 140 with 180 since the horizontal line equals 180 which gives you 40
