Answer:
<em>The slope of the line is </em><em />
Step-by-step explanation:
<u>The Slope of a Line
</u>
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
It's given the points (1,3) and (-2,2). Let's calculate the slope:
Calculating:
The slope of the line is
Answer: 222 cm
Explanation: 9x3=27x2=54
7x3=21x2=42
7x9=63x2=126
54+42+126=222
Y = 2 ( 5 ) + 3 ⇒ y = 13 :)))
