The linear equation in the graph is:
y = -6x - 1
How to find the equation?
A general linear equation is written as:
y = ax + b
Where a is the slope, and b is the y-intercept.
We can see in the graph that the line passes through (0, -1), thus the y-intercept is -1
y = ax - 1
We also can see that the line passes through (1, -7), replacing these values we get:
-7 = a*1 - 1
-7 +1 = a
-6 = a
The linear equation is:
y = -6x - 1
