Your
Step-by-step explanation:
(7,16) (3,8)
(8-16)/(3-7)
-8/-4= 2
y - 16 = 2(x - 7)
y - 16 = 2x - 14
y = 2x + 2

<u><em>An equation:</em></u>
It is used to express exact values.
Therefore, we will use an equation when when know that the quantity given is strictly equal to a given value.
<u>Examples:</u>
1- Price of a kilo of apples is $2
This is translated as ........> cost of 1 kilo = $2
2- The length of a ruler is 30 cm
This is translated as ......> length = 30 cm
<u><em>An inequality:</em></u>
It is used to show relation or compare between a quantity and a value. Therefore, we use it when we find keywords as "at least, at most, greater than, less than, ..... etc"
<u>Example:</u>
1- The distance between two cities is at least 20 miles.
This means that the distance can be 20 miles or more
This is translated as:
distance ≥ 20 miles
Hope this helps :)
