Given the equation:

y = 4x - 2

Let's graph the equation using points.

Let's create random points using the equation.

We have:

• When x = -2:

Substitute -2 for x and solve for y

y = 4(-2) - 2

y = -8 - 2

y = -10

Here, we have the point: (-2, -10)

• When x = -1:

Substitute -1 for x and solve for y.

y = 4(-1) - 2

y = -4 -2

y = -6

Here, we have the point: (-1, -6)

• When x = 0:

Substitute 0 for x and solve for y.

y = 4(0) - 2

y = 0 - 2

y = -2

Here, we have the point: (0, -2)

• When x = 1:

y = 4(1) - 2

y = 4 - 2

y = 2

We have the point: (1, 2)

• When x = 2:

y = 4(2) - 2

y = 8 - 2

y = 6

We have the point: (2, 6)

Now, we have the points:

(x, y) ==> (-2, -10), (-1, -6), (0, -2), (1, 2), (2, 6)

Plot the points on the graph and connect the points using a straight line.

We have the graph below:
