Hlep the equation r = 6t gives the number of albums released, r, by a record label over time in years, t. if you graph this relationship with time along the x-axis and the number of albums along the y-axis, which points lie on the resulting line? (7, 44) (8, 48) (9, 52) (12, 74) (13, 78)

(8,48) and (13,78)

Step-by-step explanation:

For following (t,r) points we use try and mistake method

(7,44) --> t=7, r=44   --> r=6t  --> 44=6*7  --> 44=42 (both sides not equal)  --> point (7,44) doesn't lie

(8,48) --> t=8, r=48  --> r=6t  --> 48=6*8  --> 48=48 (both sides equal) --> point (8,48) lie

(9,52) --> t=9, r=52 --> r=6t --> 52=6*9  --> 52=54  --> (both sides not equal) --> point (9,52) doesn't lie

(12,74) --> 74=6*12 --> 74=72 --> point (12,74) does't lie

(13,78) --> 78=6*13 --> 78=78 --> point (13,78) lie

(23*2)-12=x     x=34
