On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction
Karolina [17]

Answer:

b = -a

Step-by-step explanation:

We know that:

On a number line, the distance between 0 and b is the same distance that between 0 and a (but b and a are in opposite sides of zero).

And we know that, for example, when:

b = 2,  a = -2

Remember that the distance between two values is given by:

|n - m|

Then the distance between 0 and b is:

|0 - b|

and the distance between 0 and a is:

|0 - a|

we have:

|-b| = |-a|

|b| = |a|

But the numbers are in opposite sides of the zero, so one must be positive and the other negative, then we can conclude that:

b = -a

or

-b = a

(these are equivalent)

Then the correct option is the first option:

b = -a

Which strategy would you use to divide 36÷6?explain why you chose that strategy.
jolli1 [7]
36 divided by 6 is like sharing 36 orranges among 6 people
a   a   a   a   a   a|---------------------------1st Person
a   a   a   a   a   a|---------------------------2nd Person
a   a   a   a   a   a|---------------------------3rd Person
a   a   a   a   a   a|---------------------------4th Person 
a   a   a   a   a   a|---------------------------5th Person
a   a   a   a   a   a|---------------------------6th Person 

Each person receives 6 oranges evenly so 36/6 = 6
I used this strategy because it is the easiest to understand

Which is an equation of the line that has a slope of 1/2 and passes through the point (2, 4)?
irina1246 [14]

Answer:  y = \frac{1}{2}x +3  (Choice A)

Work Shown:

y - y_1 = m(x - x_1)\\\\y - 4 = \frac{1}{2}(x - 2)\\\\y - 4 = \frac{1}{2}x + \frac{1}{2}(- 2)\\\\y - 4 = \frac{1}{2}x - 1\\\\y = \frac{1}{2}x - 1+4\\\\y = \frac{1}{2}x +3\\\\

Explanation: I started with the point-slope form. Then I plugged in the given slope m = 1/2 and the point (x1,y1) = (2,4). Afterward I solved for y.

The answer is in slope-intercept form y = mx+b
