ANSWER:
(IMAGE ATTACHED)
EXPLANATION:
This equation is called a slope intercept form. The formula is y=mx+b.
"b" or -4 in this case is the y-intercept. It's where the line meets the y line (vertical line). The "m" or 2/3 is the slope. All slopes are written in y/x.
So, starting from (0, -4), you will go up 2 and go right 3. You will end up at (3, -2). Now, just draw a line through (0, -4) and (3, -2).
Your graph should show up like this:
Given:
Time spend on every 2 questions = 5 minutes.
To find:
The missing values for the given table.
Solution:
Let x be the number of questions and y be the number of minutes.
We have,
Time spend on every 2 questions = 5 minutes
Time spend on 1 question = minutes
Time spend on x questions = minutes
Now,
For x=0,
For x=1,
For x=2,
For x=3,
For x=4,
Therefore, the required table is
Questions : 0 1 2 3 4
Time (minutes) : 0 2.5 5 7.5 10
