Answer:
Intercepts are the points where a graph touches the axes. The X-intercept is that point on the X-axis, and the Y-intercept that point on the Y-axis. In the graph on the left, the X-intercept is (4,0), and the Y-intercept is (0,2)
D=rt and we are told d=546 and r=1.3m/s so
1.3t=546 divide both sides by 1.3
t=420 seconds so
420s(min/60s)=7 min
So it takes him 7 minutes to walk to Sara's house.
The greatest number in the plot is 66, and the least number is 19. If you subtract 19 from 66, the answer is 47.
The square root of 141 =

This is because the two factors are 3 and 47, which both aren't perfect squares. You cannot take anything out.
If you want it simplified (like with a calculator) it would be:
Answer:
9, y=9
Step-by-step explanation:
So, there is one thing we always need to remember to find the y intercept.
This is that the y intercept can always be found on the middle line of the graph, when x is at 0.
What we must do is look at the graph, look at where the function hits x=0, and see what the y value is.
In this case, when x equals 0, we can see that y is 9.
So the y intercept is 9.
Hope this helps! :D
