find slope first
m = (y2 - y1) / (x2 - x1)
m = (3 - (-2)) / (6 - 6)
m = 5/0. Since you can't divide by 0, the slope is undefined.
the equation is x = 6

First slope formula:
y1-y2/x1-x2
(6-3)/(-2-3) = 3/-5 = -3/5
plug this into the equation of a line = y = mx + b, where m is slope and b is y-intercept. You can use either of the points for this
3 = (-3/5)(6) + b
3 = -18/5 + b
15/5 = -18/5 + b
33/5 = b
so, y = -3/5x + 33/5

x=6?
the slope is undefiined so a conventional y=mx+b formula is not possible!
3- -2 / 6-6 = 5/0 Undefined!

just take the slope of the points. that's "m" in the y=mx+b. to find b which is the y intercept, substitute one of the coordinates in for x and y and solve for b

you can just draw the graph.Very easily you can find the answer as x=6
