Lines A and B are parallel. Lines A and B apre perpendicular to Line C.
Change all of the lines from standard form to slope-intercept.
Line A: y = 4/3x + 2/3
Line B: y = 4/3x + 2
Line C: y = -3/4x + 1
Since A and B have the same slope they are parallel. C has a negative reciprocal so it's perpendicular.
8 teaspoons, you make the ratio 1:2. then fill it in as x:16, for every 1 teaspoon of vinager you have 2 of mayo. so you'd need to make sure than x, would make 1:2 true. 8:16 is the solution because reduced it is 1:2.
(-8,1) it being reflected to the other side so just move the points
