Question 1135207: My math teacher has asked us this one complex question for points, just for fun, but it counts for points. Can someone help? I'm so stressed out!
Consider an equation of a line written in standard form: 4x - 2y = 8. Also consider a point (4, 2) that is not on that line.
(a) Find the equation of the line that is parallel to 4x - 2y = 8 and passes through the point ( 4, 2).
Write the equation is all four forms: slope-intercept, point-slope, standard, and two-point forms.
(b) Find the equation of the line that is perpendicular to 4x - 2y = 8 and passes through the point ( 4, 2).
Write the equation is all four forms: slope-intercept, point-slope, standard, and two-point forms.
(c) Graph all three lines on the same coordinate axis.
For all three lines, graph four (4) points for each line; twelve (12) points and three (3) lines total.
The first point is (4, 2), the second point is of your choosing, and the third & fourth points are
the two intercepts (vertical and horizontal); note that (4, 2) is not on the original given line so pick another point on the first line.

Question 1136039: Find the x-intercept and y-intercept of the given equation. (If an answer does not exist, enter DNE.)
y = −x
This one stumped me. I’m assuming there’s an invisible 1 in front of the negative x variable. I feel like that might be right, but I’m not sure. Unfortunately, that’s all they gave me in this question.
Also, thank you in advance to whoever solves this question!
