Answer:
In finding the sum of 2+5 you would go right on the number line, while in finding the sum of -2+(-5) you would go left on the number line
Step-by-step explanation:
We know that the total is 180 degrees of the lines.
To find x:
(5x+20)+(4x-11) = 180
x=19
To find y, input the value of x into the equation 4x-11 since this equation is equal to 2y+19
4(19)-11 = 65
2y+19 = 65
y=23
The equation would be Y=-2(x-2)+4
