Step-by-step explanation:

Given points 

( 0 , -2) and ( 4 ,10)

Slope(m) = (y2 - y1) / (x2 - x1) 

= ( 10 + 2) / ( 4-0)

= 12 / 4

= 3

Now the equation of line is 

y - y1 = m (x - x1) 

y + 2 = 3 ( x - 0)

y + 2 = 3x 

3x - y = 2

A set has 62 proper subsets how many elements has it for?

MrRissso [65]

Answer:

Step-by-step explanation:

Total number of subsets is given as

${2}^{n}$

But the subset of a set consists of the proper subsets, an empty set and the set itself.

Total number of subsets are 64

Therefore,

${2}^{n} = 64$

${2}^{n} = {2}^{6}$

Comparing both sides

$n = 6$
