Plot the following coordinates in a graph and draw a straight line that covers all three dots. (0,-2),(1,-4),(2,-6) a. What is the y value of the line when x=-1?
To plot the given coordinates (0,-2), (1,-4), and (2,-6), we can create a graph with x and y axes. The coordinates represent points on the graph.
Here's how the graph would look:
|
-8 | .
-7 |
-6 | .
-5 |
-4 |
-3 |
-2 |
-1 |
0 | .
1 |
2 | .
|___________
-2 -1 0 1 2
Now, we need to draw a straight line that covers all three dots. Since the coordinates (0,-2), (1,-4), and (2,-6) form a straight line, we can simply connect these three points to draw the line.
The line would look like this:
|
-8 |
-7 |
-6 | /
-5 | /
-4 | /
-3 | /
-2 |
-1 | /
0 | .
1 |
2 | .
|___________
-2 -1 0 1 2
Now, to find the y value of the line when x=-1, we can simply locate the point (-1, y) on the graph.
Looking at the line, we can estimate the y value when x=-1 to be approximately -3.5.
Therefore, the y value of the line when x=-1 is approximately -3.5.
