What is the slope intercept from of the equation of the line that passes through (7, -5) and (3, -9)

never [62]

Answer:

B. $y = x - 12$

Step-by-step explanation:

First, find the rate of change [slope]:

$\frac{-y_1 + y_2}{-x_1 + x_2} = m$

$\frac{5 - 9}{-7 + 3} = \frac{-4}{-4} = 1$

Then use the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done faster that way. It does not matter which ordered pair you choose:

−9 = 3 + b

−12 = b

$y = x - 12$

________________________________________________________________________________________________

−5 = 7 + b

−12 = b

$y = x - 12$

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

What is the slope of the line that goes through the points (-4,1) and (4,-5)?

LekaFEV [45]

Answer:

-4/3

Step-by-step explanation:

1. The slope formula is in the form y2-y1/x2-x1

2. Use one set of points as (x1, y1), and the other as (x2, y2).

3. Plug the points into the corresponding equation variables

4. Solve: (-4 - 4)/(1 -(-5)) = -8/6

-8/2 = -4, 6/2 = 3

-8/6 = -4/3
