Y=-7x-15
The formula to write the equation is
Y=mx+b
m=slope
m=-7
b=y intercept
b=-15
Answer:
Width of the pool = 15 yards
Step-by-step explanation:
Given that:
Length of diagonal of swimming pool = 29 yards
Length of the pool = 25 yards
Let,
w be the width.
This will form a right angled triangle where the diagonal will be hypotenuse.
Using Pythagorean theorem;

Taking square root on both sides

Rounding off to nearest whole number
w = 15 yards
Hence,
Width of the pool = 15 yards
