The number w and 0.8 are additive inverses.

umka2103 [35]

Since, the number w and 0.8 are additive inverses.

A number 'a' is said to have an additive inverse '-a' if "a+ (-a)= 0".

Since, 'w' and '0.8' are additive inverses of each other such that $w + 0.8 = 0$

Therefore, the value of 'w' should be '-0.8' so that $-0.8 + 0.8 = 0$ .

So, the value of 'w' is =0.8

Now, Refer to the attached image which represents the position of 0.8 , w ( that is -0.8) and the sum of 0.8 and w.

Sum of 0.8 and w = 0.8 + w

= 0.8 +(-0.8)

= 0.

Find the Equation of the line

romanna [79]

Answer:

$y = \frac{1}{2}x + \frac{1}{2}$

Step-by-step explanation:

Mark any two point on the line

(-1 , 0) & (-3 , -1)

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\$

$= \frac{-1-0}{-3-[-1]}\\\\= \frac{-1}{-3+1}\\\\= \frac{-1}{-2}\\\\= \frac{1}{2}$

m = 1/2 ; (-1 , 0)

Equation: $y - y_{1} =m(x -x_{1})$

$y - 0 = \frac{1}{2}(x - [-1])\\\\y = \frac{1}{2}(x + 1)\\\\y = \frac{1}{2}x + \frac{1}{2}$
