plz help. will fan and medal

Answer 1

okay.
so, first you need the slope of both lines. Slope equation is (y2-y1)/(x2-x1)
(Line 1)
2--2/1--1
4/2
2

(Line 2)

Answer 2

(1-10)/(4--2)
-9/6
-3/2

Answer 3

I). Infinitely many solutions if both lines have the same slope and the same intercept(s).

II). No solution if they have the same slope but different intercepts.

III). One solution if they have different slopes.

Answer 4

Then you can put this into slope-intercept form.
y=mx+b

(Line 1)
-2 = 2(-1) + b
-2 = -2 +b
-2+ 2 = b
b = 0
so line 1's equation is
y = 2x
