Answer:

y=1x+13

Step-by-step explanation:

First find the slope of the line.  Slope is (y2-y1)/(x2-x1). Plug in 19 for y2, 16 for y1, 6 for x2, 3 for x1. So (19-16)/(6-3) is 3/3 or 1.  The slope of the line is 1.

take the equation y=mx+b and plug 1 in for the slope (m).  Then plug in one set of points.  Using (3,16) into y=1x+b, 16=1(3) + b.  Solve for b.  B is 13.  So the linear equation is y=1x+13.
