For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It is the slope
b: It is the cut point with the y axis
We have the following equation:
Thus, the cut point with the y axis is -8. Therefore, we discard options C and B.
It is observed that the slope is positive so the correct graph is option B.
Answer:
Option B
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
step 1
Find the slope between (-3, -2) and (1, 0)
Find the equation of the line
with m and the point (1,0)
substitute
step 2
Find the slope between (-2, -1) and (4, 2)
Find the equation of the line
with m and the point (4,2)
substitute
<em>Compare the equation of the two lines</em>
The two lines are parallel, because their slope is the same, but are different lines
therefore
Beatrice's conclusion is incorrect
All of these points are not on the same line, because are different parallel lines
The slope between (-2,-1) and (1,0) is equal to
