k = -3, so this is line x = -3, included points (-3, 3) and (- 3, -2) with undefined slope
Lauren S.
The above answer k = -3 is correct, but I see you asked to know *how* to solve this problem. I'm not sure how much you remember about the equation for slope, (y = mx + b), so here's a more general explanation. Remember the slope is undefined. This means that the line is going to be vertical and will pass through the same x-coordinate value for all values of y. If we know the point (-3, -2) is on the line, and the line has an undefined slope (i.e. it is vertical), then all values of x will be -3, regardless of the y value. To solve problems with undefined slope in the general sense, plot the point (-3, -2) on a graph. Second, draw a vertical line (undefined slope) through the point (-3, -2). Lastly, take note that all points on this vertical line will be x = -3, including the point y = 3. This is why k = -3. Hope this helps, cheers!
