Answer:
y=3x+18
Step-by-step explanation:
Since slope-intercept form is y=mx+b, we first need to find the slope.
m=y2-y1/x2-x1
m=0-(-9)/-6-(-9)
m=9/3=3
Next we need to find b, or the y-intercept
to do that we plug in numbers to what we already have.
y=3x+b
0=-18+b
b=18
Now we put it all together.
<h3>y=3x+18</h3>

Answer:

Step-by-step explanation:
arithmetic sequence formula: 
where
is the first term and

Rearrange the first equation to make
the subject:
a = 32 - 9d
Now substitute into the second equation and solve for 
(32 - 9d) + 11d = 106
⇒ 32 + 2d = 106
⇒ 2d = 106 - 32 = 74
⇒ d = 74 ÷ 2 = 37
Substitute found value of
into the first equation and solve for
:
a + (9 x 37) = 32
a + 333 = 32
a = 32 - 333 = -301
Therefore, the equation is:
