Graph the line. y=-4x+7
2 answers:
The slope of the given line is -4, and the y-intercept of this line is 7.
Now, let's graph this line.
First of all, the graph crosses the y-axis at (0, 7)
Plot the point. Now, what does "the slope of the line is -4" mean?
It means we go -4 units up (4 units down) and 1 unit left/right.
"Down 4, over 1, down 4, over 1, down 4, over 1..." Continue until you have a line.
Then, all you should do is take a ruler and connect the points.
Hope it helps! Enjoy your day! :)

Answer:
Step-by-step explanation:
the probability that x iPads are defective in the sample follows a hypergeometric distribution, so it is calculated as:
Where
Because we have a N elements with k elements that are defective and we are going to take a sample of n elements. So, replacing N by 100, k by 7 and n by 3, we get:
Now, the probability of rejecting the shipment is the probability that at least one iPad of the sample is defective, so:
Then:
Finally, the probability of rejecting the shipment is:
She must start out going 8 miles per hour until the time elapsed is 1 hour at which time she drops 1.5 miles per hour. The same happens again in the second hour and the third.
The graph must have hours on the x axis and speed on the y axis.
The starting point is (0,8)
The graph must be
y = 8 - 1.5x
You need three points.

0 8
1 6.5
2 5
