Answer:
y = 2x - 9
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - (-1) / 9 - 4
10 / 5
= 2
y = 2x + b
-1 = 2(4) + b
-1 = 8 + b
-9 = b

Step-by-step explanation:
a^4-6a^2-7-8x-x^2
a^4-6a^2-8x-x^2-7
-5a^2-9x^3-7
A^2+b^2=c^2
(10.1)^2+(12.2)^2=c^2
102.01+148.84=c^2
250.85=c^2
15.8=c
Hypotenuse is approx 15.8 inches
