Determine if the point (4, −8)
lies on the line y=−2x−1
.
Enter your response in the boxes.
To determine if the point (4,-8) lies on the line y = -2x - 1, we can substitute the x and y values of the point into the equation and see if they make the equation true.
For the point (4,-8):
x = 4, y = -8
Substituting these values into the equation:
-8 = -2(4) - 1
Simplifying:
-8 = -8 - 1
-8 = -9
The equation -8 = -9 is not true, so the point (4,-8) does not lie on the line y = -2x - 1.
