For n = a million, 7^n - 2^n = 7 - 2 = 5, so the assertion is authentic for n = a million. Now anticipate the assertion is authentic for n = ok. i.e., 7^ok - 2^ok = 5*m for some integer m, and then prepare the assertion for ok + a million: 7^(ok+a million) - 2^(ok+a million) = 7*7^ok - 2*2^ok = 5*7^ok + 2*7^ok - 2*2^ok = 5*7^ok + 2*(7^ok - 2^ok) = 5*7^ok + 2*5*m = 5*(7^ok + 2m) that's divisible by using 5, thereby polishing off the evidence by using induction.

4x+2y=6
or
2x+y=3
y=3-2x
(0,3)and(1,1) satisfy
x=0
y=3-2*0=3 true
x=1
y=3-2*1=3-2=1 true

4x+2y=6
2y=-4+6
y= -2x+3
so, slope = -2
slope=(y1-y2)/(x1-x2)
choice 3):
y=mx+b
3 = -2*(0)+b
3=b
choice 3 has slope -2 and intercept 3
