Use the slope formula to calculate the slope of the line containing the points: (-2 3/4,5) and (1 3/4,3) A. m = undefined B. m=4/9 C. m =-9 D. m=-4/9

$$\sf\Large Slope = \frac{\color{blue}{y_2}-\color{red}{y_1}}{\color{green}{x_2}-\color{purple}{x_1}}$$ Where the two points are in the form: $$\sf\Large (\color{purple}{x_1},\color{red}{y_1})~and~(\color{green}{x_2},\color{blue}{y_2})$$

So, I'll just rewrite the coordinates as decimals for simplicity. (-2.75, 5) and (1.75, 3) Now, we can find the slope, m, by using the formula: m = (y2 - y1)/(x2 - x1) Let's take 3 to be our y2 and 5 to be our y1
