The y-intercept is at (0, 3)
The slope is up one, over one.
The equation for this line would be
y = 1/1x + 3
which is equal to
y = x + 3
Hope this helps!
3x + 10 + 2x -60 + 3x +23 +2x - 13 = 360
10x -40 = 360
10x - 40 +40 = 360 +40
10x = 400
10x/10 = 400/10
x = 40
3x+10 = 3(40)+10 = 130°
2X-60 = 2(40) -60 = 20°
3X+23 = 3(40)+23 = 143°
2x-13 = 2(40)-13 = 67°
