Answer:
y2-y1/x2-x1
Step-by-step explanation:
Get a line of which you want to know the slope. Make sure that the line is straight. Pick any two coordinates that the line goes through. Coordinates are the x and y points written as (x, y). Pick which point's coordinates are dominant in your equation.
Formula: Slope of a Straight Line: Point 1 is now Bert and Point 2 is now Ernie Look at the graph and note their X and Y values: (X Bert, Y Bert) and (X Ernie, Y Ernie) The slope formula is now: M = (Y Ernie - Y Bert) / (X Ernie - X Bert)
