Answer:
y = - 2 x - 3
Step-by-step explanation:
just go search 'desmos graphing calculator' to see what it would look like.
you go up two and left one, so the slope is - 2
the y-intercept is - 3 because the line crosses the y-axis at - 3
you put those two values in the right spot in the equation y=mx+b and you will get the answer of y = - 2 x - 3
