Use the slope formula to find the slope of the line that goes through the points (4, -2) and (16, 7). 5/12 3/4 9/20 4/3

Answers

Answer:

3/4

Step-by-step explanation: Using the slope formula, we know that Slope (m) = y2-y1/x2-x1 (The numbers are shown lower than the variables as subscripts). From the given two points, y2=7, y1=-2, x2=16, x1=4. 7-(-2) is 9, and 16-4 is 12. Your answer is 9/12, or 3/4 when simplified.

The slope of the line is 3/4
