Answer:
![y=-2x+9](https://tex.z-dn.net/?f=y%3D-2x%2B9)
Step-by-step explanation:
y = mx + b
The slope (m) is negative since the line is pointing downwards.
The slope is equal to rise over run. The points go down 2 over 1, which is 2/1 or 2.
B, aka the y-intercept, is equal to 9
The distance of it is half of an inch.
Considering the angle a by cosine rule
11^2 =7 ^2 +15^2 - 2(7)(15)cos(a)
When you do the maths,
Cos(a) =153/210 =0.729
a= cos inverse of 0.729
a=43 degrees
Considering angle b
7^2=15^2 +11^2 -2(11)(15) cos(b)
This will result in cos(b) =297/330=0.9
b= cos inverse of 0.9 = 25.8 degrees
Considering angle c
15^2=7^2 +11^2 - 2(11)(7) cos(c)
Cos(c) will be = -55/154 = -0.357
c= cos inverse of -0.357=110.9
Comparing the angles a,b and c,
C is the largest size in the triangle with an angle of 110.9 degrees
Am I right please ??
