Answer:
y=2x-2
Step-by-step explanation:
<em>the slope is y/x</em>
the slope is 2 or 2/1
<em>subtract 2 from the y value and 1 from the x value</em>
(3-1,4-2) = (2,2)
<em>keep doing this until you get a 0 in the x value</em>
(2-1,2-2) = (1,0)
<em>1 is your x-intercept</em>
(1-1,0-2) = (0,-2)
-2 is your y intercept.
So now you know your y-intercept and your slope so you can now write your equation.
<em>y=mx+b</em>
<em>m=slope, b=y-intercept</em>
m=2, b=-2
<em>substitute into the equation</em>
y=2x-2
The same as last time
Step-by-step explanation:
N+14=17. n=3. So the missing number is 3.
Answer:

Step-by-step explanation:
The given equality is

Take the term
to the left hand side. This means the term
will be divided by 

Now since both the numerator and denominator have negative sign the value of fraction will be positive.

Now
and 

So, the missing factor
