Question

Find the intersection point for the following linear functions. f(x) = 2x + 3 g(x) = -4x − 27Find the intersection point for the following linear functions. f(x) = 2x + 3 g(x) = -4x − 27

Answer 1

Answer: (-5, -7)

Explanation:

1. When finding the intersection you can graph it.

2. So with the g(x) you put your y coordinate are -27.

3. Then you take your -4x (this also means -1/4 like rise over run) and go over one and down 4 units also up 4 over 1. Then put a point and so on.

4. For f(x) you would start by putting your y coordinate at 3.

5. So f(x) you will need to take your 2x ( this also means 1/2 like rise over run) and go over one and down 2 or up 2 over one. Then put a point and so on.

6. Now that you have both of your lines you now can find where they intersect. Which in this case is (-5,-7).

7. Look at the graph if you're confused or if you just what to see how I did it.
