Try substituting some values in, and you will get your answer.

I'll do the first two.

y = (0) + 4 [=4]
y = (2) + 4 [=6]

In the table, the first two values for y are 6 and 8.
The first two values for y = x + 4 are 4 and 6.

Therefore, we can assume that the rate of change in the function y = x + 4 is less than the rate of change of the function represented in the table.

Your answer is less than.
When you plug in 2 into the equation, it would look like this: Y=2+4. That would make Y equal 6.
In the function, when x=2 y=8.

Referees of high school soccer games will end a game at half time if a team is ahead or behind by at least 8 goals. During the d

slavikrds [6]

If at the end of the first half, the difference between the goals scored by the applewood team and the opposing team is greater than or equal to 8, then the referee will finish the game at the end of the first half.

If we call g the number of goals scored by the opposing team, then we can express this situation as an inequality:

$11-g \geq 8\\g \leq 11-8\\g \leq 3$

However, it is impossible for a team to score -1 goal. Therefore the number of goals scored by the opposing team must be a number greater than 0.

So, the inequality is:

$g \leq 3$ and $g \geq 0$

$0 \leq g \leq 3$

The attached figure shows the graph for this inequality, which represents the number of goals that the opposing team could score if the referee finished the game in the first half.

Problem 1

Plot 3 or 4 of the given points. For example, plot (4,16) and one other point given in the table. Draw a straight line through your points. Look carefully: Where does your line cross the y-axis? If y = 14 (just an example, not the correct value), then the y-intercept is (0,14).

To find the slope of your line, choose any 2 of the given 4 points. Find the slope of the line segment connecting those 2 points. For example:
24 - 16 8
m = ------------- = -------- = 2. The slope of this line is m=2.
8 - 4 4

Now you have both the slope (2) and the y-intercept (b). The equation of this line is thus

y = 2x + b (you found b earlier).
