Answer:
b = 6
p = 4.5
n = 2.5
Explanation:
Substitute the given point (1,5.5) in the equation to evaluate b:
5.5 = -0.5 (1) + b
Simplify:
5.5 = -0.5 + b
Solve for b:
b = 5.5 + 0.5
b = 6
The equation for the line is therefore:
y = -0.5x + 6
Substitute the given point (3,p) in the equation to evaluate p:
p = -0.5(3) +6
Simplify:
p = -1.5 + 6
p = 4.5
Substitute the given point (7,n) in the equation to evaluate n:
n = -0.5(7) + 6
Simplify:
n = -3.5 + 6
n = 2.5
