If the dots are going to the right, it's positive. If they're going to the left, they're negative.

(-2,0) And (a,3) <br> Slope 3/8
UkoKoshka [18]

Answer:

a= 6

Step-by-step explanation:

slope = (y2 - y1)/(x2 - x1)

3/8 = (3 - 0)/(a - (-2))

cross multiplying,

3(a + 2) = 3(8)

3a + 6 = 24

3a = 18

a = 18/3

a = 6

What is the square root of four
xz_007 [3.2K]

Answer:

It is +2 or since (+2)*(+2 ) gives. If you think that it would be (-2) also then you are wrong because root of a positive rational number is always positive number.

Step-by-step explanation:

Let the square root of four be ‘k’.

Then we have

(4)^1/2=k

(Squaring both sides)

4=(k)^2

=>(k)^2–4=0

=>(k)^2-(2)^2=0

=>[k+2][k-2]=0 {since (a)^2-(b)^2=(a+b)(a-b)}

if product of two numbers is 0 then either of one must be zero.

If k+2=0 then k=-2

If k-2=0 then k=2

From here we got two answers but -2 should be omitted because when we square an equation we add “root extra”which means that when we square an equation one root is added.
