Question

how can i find a form for y= mx + b using (200, 100) and (50,25)

Answer 1

The slope intercept is y=0.50x+0.00

Answer 2

Answer:

The answer is

$y = \frac{7}{2}x - 600$

Step-by-step explanation:

Formula:

$y = mx + b$

We first need to find the slope:

$m = \frac{25 - 200}{50 - 100} = \frac{ - 175}{ - 50} = \frac{7}{2}$

Now we need to find the y-intercept:

y = mx + b (substitute)

100= 7/2(200) + b

100 = 700 + b

-700=-700

-600 = b

Using the information we now have:

$y = \frac{7}{2}x \: - 600$
