Y=mx+b, m=(y2-y1)/(x2-x1)
m=(7-4)/(6--3)=3/9=1/3
y=x/3 +b, now use either point to solve for b, I'll use (6,7)
7=6/3 +b
7=2+b
b=5 so our line is:
y=x/3 +5 or more neatly...
y=(x+15)/3
Answer
B
Step-by-step explanation:
Multiply all the Number of Board Games by 3.5. It is the same as the Price already showed on the graph. So, the correct answer is B.
0.1
the 0 is in the thousandths place plus the 2 os next to is since 2<5 it is 0

- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 15
Hypotenuse <em>c</em> = 25
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: x² + 15² = 25²
- Isolate <em>x</em> term: x² = 25² - 15²
- Exponents: x² = 625 - 225
- Subtract: x² = 400
- Isolate <em>x</em>: x = 20
