Answer:
Step-by-step explanation:
(3-7)/(-2+1)= -4/-1= 4
y - 7 = 4(x + 1)
y - 7 = 4x + 4
y = 4x + 11
![x^2 - 4x - 9 = 29 \\ x^2 - 4x - 9 - 29 = 0 \\ x^2 - 4x - 38 = 0 \\ x= \frac{-b \pm \sqrt{ b^{2} -4ac} }{2a} ](https://tex.z-dn.net/?f=x%5E2%20-%204x%20-%209%20%3D%2029%20%5C%5C%20x%5E2%20-%204x%20-%209%20-%2029%20%3D%200%20%5C%5C%20x%5E2%20-%204x%20-%2038%20%3D%200%20%5C%5C%20x%3D%20%5Cfrac%7B-b%20%5Cpm%20%20%5Csqrt%7B%20b%5E%7B2%7D%20-4ac%7D%20%7D%7B2a%7D%20%0A)
; where a = 1, b = -4 and c = -38
