Sorry, not doing your entire assignment for you.  One problem per post.

*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ 4y\ =\ 8]

Substitute a zero for *[tex \Large x], and then calculate the resulting value of *[tex \Large y\ =\ b].  Plot the point *[tex \Large (0,b)]

Substitute a zero for *[tex \Large y], and then calculate the resulting value of *[tex \Large x\ =\ a].  Plot the point *[tex \Large (a,0)]

Draw the line through your two plotted intercept points.

*[tex \LARGE e^{i\pi} + 1 = 0]
