From -4 to 1 (range equals the y values)
You can set them equal to each other so -3x+4=4x-10 and then you add 3x and 10 on both sides and get7x=14 and then divided both sides by 7 and get x = 2 and check by plugging in and you get -2 for y on both so solution is x=2
The ratio being 1:5:3, you would have to just make those numbers still in that ratio, but they have to add up to 180 degrees.The angles would be 20 degrees, 100 degrees, and 60 degrees. Hope that helped. :)
