Answer:
two is the last one, three us the first one, and four is the second one, and six is the definition of parallelogram
The slopes must be the same. From a table you can calculate the slope of a line segment connecting any two of the given points. Note that this slope must be consistent throughout.
From a graph, you can find the exact slope of the line, or estimate it closely.
If the slopes are the same in both graphs, the two lines are parallel to one another.
1 journal = 280 grams
3 journals = 280 * 3
280 * 3 = 840
Total weight of 3 journals = 840 grams

Answer:

Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept(value of y when x = 0).
If two lines are perpendicular, the multiplication of their slopes is -1.
Contains (0, 2)
This means that
. So

Finding the slope:
Perpendicular to y = 2/3x + 1 means that:



So
