Given:

The graph of a trend line.

To find:

The equation of the trend line.

Solution:

From the given graph it is clear that the trend line passes through the points (0,4) and (9,7). So, the equation of the trend line is:

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-4=\dfrac{7-4}{9-0}(x-0)$

$y-4=\dfrac{3}{9}(x)$

$y=\dfrac{1}{3}x+4$

Therefore, the equation of the trend line is $y=\dfrac{1}{3}x+4$ .

How do you solve <br>m=q/z-v solve for z

g100num [7]

Hello!

To solve whatever z is we have to get it by itself by using inverse operations. I will undo operations below.

m=q/z-v+v
m+v=q/z(z)
m+v+z=q
m+v+z-z=q-z
m+v=q-z
Here I will switch z to adding negative z so we can use the commutative property.
m+v= q+(-z)
m+v=-z +q
m+v-q=-z+q-q
m+v-q=z

We now have our formula for z. z=m+v-q. Hope this helps!
