please help will fan and medal.

Answer 1

Line 1: (-1,-2) and (1,2)
Line 2: (-2,10) and (4,1)
----
Get equations of the lines.
Line 1: (-1,-2) and (1,2)
Find the slope, m
m = diffy/diffx = (-2-2)/(-1-1) = 2
Use y = mx + b and either point to find b, the y-intercept
Using (1,2): 2 = 2*1 + b --> b = 0
y = 2x is an equation of Line 1
----
Get the eqn of line 2 the same way.
