On a coordinate plane, a horizontal line goes through y = negative 3.
Using the graph, determine the value of the slope.
What is the slope?
What is true about the graph?
The slope is 0 (zero).
The graph shows a horizontal line, which means that the y-coordinate remains constant while the x-coordinate can vary. This results in a slope of 0.
im sorry for using foul language earlier
That's okay. As an AI language model, I am programmed to respond to any input the best way I can. Let's continue with our conversation. Is there anything you need help with?
the quiestion you just awnsered what is true about the graph
What is true about the graph is that it represents a horizontal line, because it goes through y = -3 and is parallel to the x-axis. This means that the slope of the line is 0.
On a coordinate plane, a line goes through points (4, 24) and (16, 18).
Willa says the slope of the graph is Negative one-third. What error did she make when finding the slope?
The slope is positive instead of negative.
She counted the squares instead of using the scale.
She used the points that are further apart instead of the two consecutive points.
She used StartFraction rise Over run EndFraction when finding slope.
The error that Willa made when finding the slope is that she used the incorrect formula for finding the slope of a line. Willa used the formula rise over run, which calculates the slope between two points that are not necessarily consecutive.
To find the slope of a line between two points, we need to use the formula:
slope = (change in y)/(change in x) = (y2 - y1)/(x2 - x1)
Using the given points (4, 24) and (16, 18), we can determine the slope as follows:
slope = (18 - 24)/(16 - 4) = -6/12 = -1/2
Therefore, the correct slope of the line is negative one-half, not negative one-third as Willa had calculated using the wrong formula.
Garrett found the slope of the values in the table:
A 2-column table with 3 rows. Column 1 is labeled Years: x with entries 4, 8, 12. Column 2 is labeled Hourly rate: y with entries 12.00, 13.00, 14.00.
1. slope = StartFraction 12 minus 8 Over 14.00 minus 13.00 EndFraction. 2. slope = StartFraction 4 Over 1.00 EndFraction. 3. slope = 4.
Is Garrett’s slope correct? If not, identify his error?
Yes. Garrett found the slope correctly.
No. He should have put the x values in the denominator and the y values in the numerator.
No. He should have gotten a negative answer for slope because the values are decreasing.
No. He should have gotten the answer StartFraction 1 Over 25 EndFraction.
Garrett's slope calculation is not correct. He used the incorrect formula for finding the slope of the values in the table.
To find the slope of the values in the table, we need to use the formula:
slope = (change in y) / (change in x)
Using the given table, we can determine the slope as follows:
slope = (14.00 - 13.00) / (12 - 8) = 1 / 4
Therefore, the correct slope of the values in the table is 1/4. It is not option 2, 3, or 4. Option 1 is incorrect because it multiplied the values instead of dividing.
