Answer:
y = -13x + 49
Explanation:
y = mx + b (by looking at the y values as you subtract 13 every time and x goes up by one we know the slope is -13) --> then plug in one of the points to find the b value:
-3 = -13(4) + b
-3 = -52 + b
49 = b
sorry that this isn't very in depth so lmk if you have any questions but it seems like you needed it fast so here you go. (if you ever need to check an equation plug in one of the x or y-values into the equation you made to make sure it works)
