Question

On a coordinate plane, line D F goes through points (negative 1, negative 3) and (2, 3). Point G is at (negative 4, negative 4). Which point on the y-axis lies on the line that passes through point G and is parallel to line DF? (–2, 0) (0, –2) (0, 4) (4, 0)

Answer 1

(C) (0-4)

Explanation:

Answer 2

The line passes through the y-axis at point (0,4).

Explanation:

On a coordinate plane, line DF goes through points (-1,-3) and (2,3).

So, the slope of the line DF is
`(- 3 - 3)/(- 1 - 2) = 2`

Then the straight line which is parallel to DF will be given by

y = 2x + c.

Where, c is any constant and we have to evaluate it if this line passes through the point (-4,-4).

So, - 4 = 2(- 4) + c

⇒ c = 4

So, the straight line which is parallel to DF and passes through the point (-4,-4) is y = 2x + 4.

Now, putting x = 0, we get, y = 4.

Therefore, the line passes through the y-axis at point (0,4). (Answer)
