The problem is to find the slopes and -intercepts of the following lines:
I know that for the -intercept we should set equal to zero and solve for . For example, the y intercept for is and slope is . For the first equation, which is a line parallel to the y-axis and never crosses it, I think the y-intercept is undefined (or maybe zero) and also the slope is the same.
But for the second equation, the y-intercept is (because it crosses at point for all values of ). But I think that the slope is undefined. I think this because if we compare to (where is the slope), then we can't determine a simple slope.
