Answer:
a = 6
b = 3/4
Step-by-step explanation:
They both need to have the same slope.
The slope in the first equation is 6
That means that the second equation must have a = 6
They both need to have the same y intercept
The second equation has a y intercept of 3/4
Therefore b in the first equation, must be 3/4
X=120
2/5-(x/300)=0
Simplify= X/300
2/5-X/300=0
Simplify=2/5
2/5-X/300=0
The left denominater is: 5
The right denominater is: 300
