The graph of a line goes up and to the right when: A. the coefficient of x is 0.
Ο Ο Ο
B. the coefficient of x is negative.
C. the coefficient of x is positive.
D. there is no coefficient of x.

C, the co-efficient of x is positive

Step-by-step explanation:

Since you are going rise/run to go up, you have to have a positive coefficient. it could be a fraction, such as 2/9(up 2 and over 9) which is still going up and to the right

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
