A. x^2 = 15^2 - 9^2
Here's why:
c^2 = a^2 + b^2
from the question:
15^2 = 9^2 + x^2
15^2 - 9^2 = x^2 which is similar to answer in A.
Start on the y-axis and put a point at 490 bc it the y-intercept and then from there go up 2 and right 3 and put a point there and keep going and to go down you just go down 2 and left 3 and the point it.

Answer:
y = 147.56 - 10.78x
Step-by-step explanation:
Given :
x = 10.2 ; y = 37.6 ; Sx = 2.8 ; Sy = 30.8 ; r = - 0.98
The regression equation :
y = mx + c
Where ;
m = slope ; c = intercept
Slope = r * (Sy/Sx)
Slope = - 0.98 * (30.8 / 2.8)
Slope = - 0.98 * 11 = - 10.78
To obtain c :
y = mx + c
y - mx = c
37.6 - (-10.78)(10.2) = c
37.6 + 109.956 = c
147.556 = c
Hence, equation becomes :
y = 147.556 - 10.78x
y = 147.56 - 10.78x
