Answer:
y=1/2x-2
Step-by-step explanation:
1. Find slop by subtracting y values over subtracting x values, which will get you the m value
-1+3 / 2+2 = 1/2
Answer: 15
Step-by-step explanation: 5/9=15/27. 27-15=12
Answer:
y=7(x-5)+3
Step-by-step explanation:
Step-by-step explanation:
2πr is the formula is because the radius of a circle or a face of a circular object is used more often than the diameter. For example, the area of a circle is πr^2.
The proportion is simply a matter stating the ratios as fractions, setting two fractions equal each other and cross multiplying.
For example:
2/x=3/9.
You need to cross multiply in order to get your answer. so 9(2)=x(3)
18=3x
6=x.
Thats how you solve a proportion.
Hope this helped :)
Have a great day
