A line includes the points (9,0) and (-9,2). What is its equation in slope-intercept form?
horsena [70]
Y=mx+b

First use the two point slope formula to find m

(y2-y1)/(x2-x1)
(2-0)/(-9-9)
2/-18
1/-9=m

Next use the point slope formula to find the answer

y-y1=m(x-x1)

y-0=1/-9(x-9)

Now use Distributive Property 
y-0=1/-9(x)+1/-9(-9)
y-0=1/-9x+1

Your answer would be 
y=-1/9x+1

Look at the picture! Express the following set in set-builder notation ?
Alex

Answer:

A.   E={x|x\in N and x is a multiple of 8}

Step-by-step explanation:

Let x represent the set of natural numbers. Then we can write;

x\in N.

The set of all natural numbers that are multiples of 8 is then written as;

x\in N and x is a multiple of 8.

E is the set of natural numbers that are multiples of 8 can then be written in set builder notation as;

E={x|x\in N and x is a multiple of 8}

The correct choice is A

What number is 53% of 470
Kazeer [188]

The word "of" is the same thing as a multiplication sign!


So instead see it this way:


53% × 470


To solve this, you can use the cross product method :


\frac{53}{100} = \frac{?}{470}


(470 × 63) ÷ 100 = ?


29 610 ÷ 100 = ?


296.1 = ?


53% of 470 is 296.1


There you go! I really hope this helped, if there's anything just let me know! :)
