Answer:
The answer is
[tex]y = \frac{7}{2}x - 600[/tex]
Step-by-step explanation:
Formula:
[tex]y = mx + b[/tex]
We first need to find the slope:
[tex] m = \frac{25 - 200}{50 - 100} = \frac{ - 175}{ - 50} = \frac{7}{2} [/tex]
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:
[tex]y = \frac{7}{2}x \: - 600[/tex]
