Question

(12,-9) and (-2,-2) in slope intercept form and if u want the points please explain how u got it

Answer 1

Answer:

$y= -\frac{1}{2} x-3$

Step-by-step explanation:

Slope intercept form :

y = mx + b

m is the slope

b is the y-intercept

Let's look for m, use the formula $\frac{(y_{1}-y_{2} ) }{(x_{1} -x_{2} )}$ to determine it.

$\frac{-9 - (-2)}{12 - (-2)}$ $= -\frac{1}{2}$

$y = -\frac{1}{2}x+b$

Now find b, we simply need to plug in one of our coordinates to get our answer.

(12, -9)

$-9=-\frac{1}{2} (12)+b$

Solve for b :

-9 = -6 + b

-3 = b

b = -3

Our slope intercept is :

$y = -\frac{1}{2}x - 3$
