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! :)

Step-by-step explanation:
Given
Required
Draw the rectangle
First, we calculate the distance between A and B using distance formula;
So, we have:
The above represents the length of the triangle.
Next, calculate the width using:
Divide both sides by 2
This implies that, the width of the rectangle is 6 units.
We have:
Since A and B are at the upper left and right, then the ther two points are below.
6 units below each of the above point are:
=>
=>
Hence, the points of the rectangle are:

Given:
Initial mass, m₀ = 23 g
Decay constant, k = 0.13
Exponential decay obeys the equation
where t = time, days
For half life, the mass is m = m₀/2.
Therefore
Answer: The half life is 5.33 days
