Write the equation of the line, in point-slope form. identify (x1, y1) as the point (1, 2). use the box provided or the upload option to submit all of your calculations and final answer.

We are given with the coordinates of one of the points of a line which is
(1,2)
In order to generate an equation of a line, we need at least one other point or the slope of the line. If we are given with the slope of line, we can use the point slope form which is
y - y1 = m (x - x1)
substituting
y - 2 = m(x - 1)

What is the diagram u didn't post that
