The lines mean that the number is going to become positive. |-178| will become positive meaning it will become= |178|
1st piece = x
2nd piece = x+2
3rd piece = x+2+3 = x+5
37 = x +x+2 + x+5 =
37 = 3x+7
30=3x
x = 30/3 = 10
1st piece = 10 inches
2nd piece = 10+2 = 12 inches
3rd piece = 10+5 = 15 inches
Answer:

Step-by-step explanation:
Finding the slope (m) of the line the following points in the line, (0, 0) and (2, 20):

y-intercept (b) is 0. The line intercepts the y-axis at 0. Thus, b = 0.
Substitute m = 10 and b = 0 in 
The equation in slope-intercept form for the graph would be:
✅

Answer:
