Answer 2

To find the intersection points of the given equations, we need to solve them simultaneously. Let's find the values of x and y that satisfy all four equations.

1. y = -2x - 1
2. y = -x + 4
3. y = 6x - 3
4. y = x + 2

We can start by solving the first two equations:

Equation 1: y = -2x - 1 Equation 2: y = -x + 4

Since both equations are equal to y, we can set them equal to each other:

-2x - 1 = -x + 4

Now, let's solve this equation:

-2x + x = 4 + 1 -x = 5

Divide both sides by -1:

x = -5

Substitute this value of x into either of the original equations (let's use Equation 1) to find y:

y = -2(-5) - 1 y = 10 - 1 y = 9

So, the first intersection point is (-5, 9).

Next, let's solve the third and fourth equations:

Equation 3: y = 6x - 3 Equation 4: y = x + 2

Set them equal to each other:

6x - 3 = x + 2

Solve for x:

6x - x = 2 + 3 5x = 5 x = 1

Substitute this value of x into either of the original equations (let's use Equation 3) to find y:

y = 6(1) - 3 y = 6 - 3 y = 3

So, the second intersection point is (1, 3).

In summary, the intersection points of the given equations are: (-5, 9) and (1, 3).
