Answer:

You can manipulate both equations into y = mx + b format and end up with the same result of y = 1.2x + 1.4

Step-by-step explanation:

y + 1 = 1.2(x + 2)

y = 1.2x + 2.4 - 1

y = 1.2x + 1.4

y - 5 = 1.2(x - 3)

y = 1.2x - 3.6 + 5

y = 1.2x + 1.4

So essentially, they're the same equation but in different forms.

KonstantinChe [14]

The 0.8% of the production is defective if a quality control process finds 77.6 defects for every 9,700 units of production.

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

A quality control process finds 77.6 defects for every 9,700 units of production.

The percent of the production is defective:

\rm = \dfrac{77.6}{9700}\times 100

= 0.8 %

Thus, the 0.8% of the production is defective if a quality control process finds 77.6 defects for every 9,700 units of production.
