Answer:

y = 4x -3

Explanation:

Here, we want to get the equation of the blue line

As we can see, the y-intercept is -3

So we have the equation as;

y = mx -3

To get the value of m which is the slope , we check for any point on the line

That would be;

(1,1)

Let us have this substituted;

1 = m(1) - 3

1 = m -3

m = 1 + 3

m = 4

so the equation of the straight line is;

y = 4x -3
