Question

The point (3,-1) is on the line given by which equation below?

a) y = -3x
b) y = 3x
c) y = x - 4
d) y = x + 4

Answer 1

The point (3,-1) does not lie on the line represented by the equation y = x + 4.

Step-by-step explanation:

The point (3,-1) is on the line given by the equation y = x + 4. To determine this, we can substitute the x and y coordinates of the point into the equation and check if they satisfy it.

Using the coordinates (3,-1), we substitute x = 3 and y = -1 into the equation y = x + 4:

-1 = 3 + 4

-1 = 7

Since -1 does not equal 7, the point (3,-1) does not lie on the line represented by the equation y = x + 4. Therefore, the correct answer is d) y = x + 4.
