Plot three points with first coodinate equal to (-2.8) and join them
ok. now what?
(-2.8,0),(-2.8,-5),(-2.8,1.73)
To plot the three points with the first coordinate equal to -2.8, you would need the coordinates for the other two points. Let's assume the three points have coordinates (-2.8, y1), (-2.8, y2), and (-2.8, y3).
You can choose any values for y1, y2, and y3. For simplicity, let's use y1 = 1, y2 = 2, and y3 = 3.
Plot the three points:
Point A: (-2.8, 1)
Point B: (-2.8, 2)
Point C: (-2.8, 3)
Now, join these points on a graph by drawing lines connecting them. Since all three points have the same x-coordinate (-2.8), the lines will be vertical.
The resulting plot will have three vertical lines on the x-axis, intersecting it at -2.8, and extending upward to y-values of 1, 2, and 3, respectively.
