How do I graph y = 9x?

Slope intercept form is y=mx+b. since there is no b term, the y intercept is 0. since there is a 9 in the m term, your slope will be nine. based on those two things, you need a point at (0,0) and (1,9). on the other end, your point will be (-1,-9). then draw a straight line through. hope this helps :)

In April 2008, an audio CD was available for $14.01. the list price (full price) of the CD was $19.32. What was the percent disc

8_murik_8 [283]

19.30 - ( p / 100 )*19.32 = 14.01 ;
19.30( 1 - p/100 ) = 14.01 ;
1 - p/100 = 14.01 / 19.30
1 - p / 100 = 0.72 ;
p/100 = 1 - 72 / 100 ;
p/100 = 28 / 100 ;
p = 28 ;
The percent discount is 28% ;

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

13x - 6y = 22

x = y + 6

Step 2: Solve for y

Substitution

Substitute in x: 13(y + 6) - 6y = 22
Distribute 13: 13y + 78 - 6y = 22
Combine like terms: 7y + 78 = 22
Isolate y term: 7y = -56
Isolate y: y = -8

Step 3: Solve for x

Define original equation: x = y + 6
Substitute in y: x = -8 + 6
Add: x = -2
