Explanation / Answer

a) The slope of the line is not determined by the intercept but by the slope.

Therefore, the line slopes downwards because the slope is negative.

b) The equation of any line with intercept K and slope M is obtained as:

y = Mx + K

Therefore, the equation of lines here would be given as:

y = - 0.5 x + 0

That is y = - 0.5x

c) Two points that could be plotted here are given as: (0, 0) that is at the origin and second point being at (x = 1 , y = - 0.5 )
