Y=mx+b
m=slope
paralell ines have same slope
y=2/3x-6
slope is 2/3
the equation of aline that passes through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
(3,14) and slope is 2/3
y-14=2/3(x-3)
y-14=2/3x-2
y=2/3x+12

Answer:
- absolute error: 0.4 kg
- relative error: 6.1%
Step-by-step explanation:
The absolute error is the difference between the estimate and the actual weight:
7.0 kg -6.6 kg = 0.4 kg . . . . absolute error
__
The relative error is the ratio of the absolute error to the actual weight:
(0.4 kg)/(6.6 kg) × 100% = 6.060606...% ≈ 6.1% . . . . relative error
Step-by-step explanation:
<span>(x+3)^2 = x^2 + 69
x^2 + 6x + 9 = x^2 + 69
x^2 + 6x + 9 - x^2 = x^2 + 69 - x^2
6x + 9 = 69</span>
