Answer:
Step-by-step explanation:
The line is shown in the attachment.
The slope of this line is given by:
The line passes through (0,1) and (1,5)
Plug in the points to get:
The equation of this line is given by , where b=1 is the y-intercept.
From the graph the y-intercept is 1, because the line intersects the y-axis at (0,1).
Therefore the equation is
Answer:
He subtracted -5 from both sides, not -6
Step-by-step explanation:
The inequality that we have to solve in this problem is
To solve the inequality, we proceed as follows:
1)
First, we isolate the term in x. To do that, we add -6 on both sides of the inequality, and we find:
So, this is now the new inequality.
2)
Then, we divide both sides of the equation by 5; we get:
3)
Finally, we change sign to the inequality, so we get:
So, the student's error is that he subtracted -5 from both sides, not -6.
