Why might using a graph to find the slope be inefficient?

• Graphs are time-consuming

• Graphs can be inaccurate

• Graphs are not always available

• Graphs are difficult to draw

What does the slope formula look like?

• m = (X2 - X1) / (Y2 - Y1)

• m = (Y2 - Y1) / (X2 - X1)

• m = (X1 - X2) / (Y1 - Y2)

• m = (Y1 - Y2) / (X1 - X2)

In the slope formula, what does 'm' represent?

• The midpoint

• The slope

• The x-intercept

• The y-intercept
