Use slope formula to find slope
<span><span><span>−9−5</span><span>−/12−8</span></span>=<span><span>−14/</span><span>−20</span></span>=<span>7/10</span></span>
7/10 = m = slope
y= mx + b
y= (7/10)x + b
(8,5)
(5) = (7/10)(8) + b
b = -3/5
So....
<span>y=(<span>7/10)</span>x −<span>35
</span></span>
multiply by 10
<span>10y=7x−6</span><span>
--> -7x + 10y = -6
--> 7x - 10y = 6
So, if 7x - 10y = 3 a good model?</span>
|2.5| because 2 and 1/2 are also 2.5 written in decimal, and the absolute value is always positive
Start at (0, 135) and work your way down 15 and over one each time. Your next point would be (1, 120)
Answer:
21x + 35y
Step-by-step explanation:
Distribute the 7 to everything in the parentheses.
7*3=21
7*5=35
