Use the law of Cosines where
angle A = 14+22=36 degrees
side b = 6 times 7
side c = 6 times 19
So you have a triangle with 2 legs of 42 and 114 with angle A = 36 degrees between them.
The law of Cosines is then
a^2 = 42^2 + 114^2 - 2(42)(114)Cosine(36)
Solve and take the square root.

Answer:
![{ \tt{y = \frac{ - 3}{4}x - \frac{2}{5} }} \\](https://tex.z-dn.net/?f=%7B%20%5Ctt%7By%20%3D%20%20%5Cfrac%7B%20-%203%7D%7B4%7Dx%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20%20%7D%7D%20%5C%5C%20)
• for y-intercept, x is zero
![{ \tt{y = ( \frac{ - 3}{4} \times 0) - \frac{2}{5} }} \\ \\ { \tt{ y = - \frac{2}{5} }}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7By%20%3D%20%28%20%5Cfrac%7B%20-%203%7D%7B4%7D%20%20%5Ctimes%200%29%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20%7D%7D%20%5C%5C%20%20%5C%5C%20%7B%20%5Ctt%7B%20y%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20%7D%7D)
• therefore:
![{ \tt{y - intercept : \: (0, \: - \frac{2}{5} ) }} \\](https://tex.z-dn.net/?f=%7B%20%5Ctt%7By%20-%20intercept%20%3A%20%5C%3A%20%280%2C%20%5C%3A%20%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20%29%20%7D%7D%20%5C%5C%20)
