Answer:
Line 1: -2
Line 2: 2
Line 3: 2
Line 1 & 2 is parallel.
Line 2 & 3 is neither.
Step-by-step explanation:
To find the slope of a line use the slope formula and substitute the points into it:
Line 1

Line 2

Line 3

Parallel lines have the same slope and perpendicular lines have negative reciprocal slopes.
Line 1 & 2 is parallel.
Line 2 & 3 is neither.

Answer:
Step-by-step explanation:
We begin with m(x) = 3^x.
Then -m(x + 1) = -3^(x + 1). Here we've inserted the ' - ' sign and replaced x with (x + 1).
12/15 divide both by 3=4/5
48/56 divide both by 8 =6/7
28/36 divide by 4 = 7/9
15/40 divide by 5 = 3/8
