The data is linear as the x and y are both increasing at a set amount. 
X increases by 2 each time Y increases by 4. 
Our slope would be 2x because every time x goes up 1 y goes up 2. 
With that knowledge I can figure that if you increased the point -1,17 by the slope to get 0,21 that would be the  y intercept. 
Thus the equation should be y=2x+21

The sum of twice a number and four times the number is 54. Find the number.
miv72 [106K]
Twice a number can be written as 2n.

Four times the number can be written as 4n.

If the sum of 2n and 4n equals 54, then:

6n = 54

Divide both sides by 6 to solve for n:

n = 9

How can you quickly determine the number of roots a polynomial will have by looking at the equation?
Alika [10]
Suppose we have a generic polynomial of the form:
 ax ^ 2 + bx + c

 To know how many roots the polynomial can have, the first thing you should do is observe the term of greatest exponent.
 For this case, the term of greatest exponent is 2.
 Therefore, the polynomial has 2 roots.
 Answer:
 
You must observe the term of the polynomial with greater exponent.
