Answer:

y = x +7

Explanation:

The slope of the given line can be found as ...

m = (y2 -y1)/(x2 -x1)

m = (3 -7)/(-1 -3) = -4/-4 = 1

Then the point-slope form of the equation for the desired line is ...

y -k = m(x -h) . . . . . . line with slope m through point (h, k)

y - 9 = 1(x -2)

y = x -2 +9

y = x + 7 . . . . slope-intercept form

__

The attachment shows a graphing application that will write the equation of the line. Here, it shows the desired line has the equation ...

x -y = -7 . . . . desired line equation in standard form
