Hello,
The rate of change is the slope (rise/run, y/x). To find that, we use the equation (y2-y1) over (x2-x1). It means take the second "y" and subtract it from the first "y" and the same to "x". If I plug in the numbers, it would be (3-6) over (5-4), and after you subtract, the answer simplifies to: -3/ 1 which is -3. Yay! We got the slope (rate of change) done.
Now let's find the y-intercept by using the formula of point-slope form,
y-y1= m (slope) (x-x1). This is saying you "y" is subtracted from the first
"y" of the points which equals the slope (m) times the quantity of "x" subtracted by the first "x" of the points.
Let's plug the numbers in: y-6 = -3 (x-4). Let's distribute -3 to the parenthesis, and after that it should simplify to: y-6 = -3x + 12. To get "y" by itself, add 6 to both sides: y = -3x +18. We have finally found the slope-intercept equation for those two points (4,6) and (5,3). To then find the y-intercept in this equation, it would be the 18, because -3 is the slope, so that makes 18 the y-intercept.
In conclusion, the rate of change is -3 and the y-intercept is 18.
I hope this helps!

Answer:
Step-by-step explanation:
To find the average of 4 things, we add those four things together and divide by 4. So, here we need to do the opposite. Since the last thing we would do to find the average is divide by four, we are going to start there and do the opposite. The average is 166. So...
166X4=664
Now instead of adding, we will subtract the three that we know, leaving the fourth. 664-200=464 464-150=314 314-180=134
So the weight of the fourth person is 134 pounds.
0.608 because each decimal number after 0 represents a place. example, 0.6 would be said as 6 tenths.
