Hello!
The equation for a line is y = mx + b
m is the slope
b is the y-intercept
The y-intercept is -3
y = mx - 3
To find the slope you count how many times up and over it goes from point to point
It goes up one over one
[tex]y = \frac{1}{1} x - 3[/tex]
Simplify
The answer is y = x - 3
Hope this helps!
