Please ill give u 20 point plus brainlist

Slope = 3

Step-by-step explanation:

This line is proportional, so constant = slope

For the point (1,3), the constant would equal 3

The slope is = constant so slope = 3

The slope of the line is 3

Step-by-step explanation:

Select two points on the line and find the slope. I will use (0,0) and (2,6) to demonstrate as (x1,y1) and (x2,y2) respectively:

Slope = Rise/Run = (y2-y1)/(x2-x1) = (6-0)/(2-0) = 6/2 = 3

Therefore, the slope of the line is 3.
