Answer:
1
m = ---
12
Step-by-step explanation:
The formula is y2-y1
---------
x2-x1
(x1,y1) (x2,y2)
(3,-5) (-9,-6)
You get the 2 Y's and subtract them
Do the same with the X's
Y's above , X's below
(y2- y1)
⬇
-6-(-5) -1 1
--------- = ---- = ---- = m
-9-(3) -12 12
⬆
(×2- x1)
This equation is backwards, thats why it was harder to understand. (-9,-6) is farther left and below point (3,-5), making it the REAL first point in the equation.
This is just a statement. Please, we need a question to answer
This is how your answer would look like in vertex form:
y= -2 (x - 1)^2 + 8
Answer:
Step-by-step explanation:
Hi there!
Slope-intercept form: 
where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x is 0)
<u>1) Plug in the slope (</u><u><em>m</em></u><u>)</u>
We're given that the slope is 
. In , replace <em>m</em> with :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
We're given the point (-9,4). Plug this point into the equation as 
and solve for <em>b</em>:
Subtract 
from both sides to isolate <em>b</em>:
Therefore, the y-intercept is . Plug this back into as <em>b</em>:
I hope this helps!
