Slope = (y2 - y1)/(x2 - x1)
Let's plug in our values: (10 - 9)/(5 - - 6)
This gives us 1/11 as our slope.
Answer: ITS A! I HAVE THE SAME TEST!
Step-by-step explanation:
Answer:
4(x - 1) = 4x - 4
3x + 6 = 3(x + 2)
Step-by-step explanation:
The first equation is
We simplify to get;

This is always true. The equation has infinite solution.
The 5th equation is:
This also has infinite solution
The 6th equation is
It has a unique solution.
Answer:
x+y= 120
90x+250y=27,600
Step-by-step explanation:
x= number of certain tickets
y= number of remaining tickets
The statement indicates that for a particular flight the airline sold 120 tickets which means that the sum of the different tickets is 120. The first equation is:
x+y= 120
Then, the statement says that certain number of tickets costs $90 and the remaining tickets cost $250 and that for a particular flight, the airline collected $27,600. From this, you can say that the number of certain tickets, x, multiply for its price that is $90 plus the number of the remaining tickets, y, multiply for its price that is $250 would be equal to $27,600. The equation would be:
90x+250y=27,600
According to this, the answer is that the system of equations that represents this relationship between x and y is:
x+y= 120
90x+250y=27,600
Answer:
what makes a graph linear:
• it's a straight line
• has a constant rate of change (slope)
• and of course it runs once through the y axis.
