Respuesta :
The slope of the line having the points (-1,-1) and (3,15) is 4.
What is slope of a line?
The slope of a line between two points says (x1,y1) and (x2,y2) will be easily determined by finding the difference between the coordinates of the points.
How to calculate slope of a line?
The formula to calculate the slope of a line having points (x1,x2), (x2,y2) is (y2-y1)/(x2-x1)
Slope of points (-1,-1) (3,15) =[15-(-1)]/[3-(-1)]
=16/4
=4
Hence the slope of line having points (-1,-1) and (3,15) is 4.
