This is the form of a linear equation.
y=mx+b
If we try to find w through this we get... two variables.
w=-1(6)+b
So, to find out w we need b first.
What does b represent? It is the y-intercept of the line. We can find that using point (-2,6) the slope of -1.
6=-1(-2)+b
b=4
Now back to the first step.
w=-1(6)+b
w=-1(6)+4
w=-2
answer: -2
