Determine which ordered pair is a solution of y=x+2/5.
A(0,0)
B(-1,2/5)
C(1,2/5)
D(2,2 2/5)
What is your answer?
Honestley I have no idea how to do this.
To determine which ordered pair is a solution of the equation y = x + 2/5, we need to substitute the values of x and y from each ordered pair into the equation and see if the equation holds true.
Let's go through each option:
A(0,0):
When x = 0 and y = 0, we have:
0 = 0 + 2/5
0 = 2/5
Since 0 is not equal to 2/5, A(0,0) is not a solution to the equation.
B(-1,2/5):
When x = -1 and y = 2/5, we have:
2/5 = -1 + 2/5
2/5 = 2/5
Since 2/5 is equal to 2/5, B(-1,2/5) is a solution to the equation.
C(1,2/5):
When x = 1 and y = 2/5, we have:
2/5 = 1 + 2/5
2/5 = 7/5
Since 2/5 is not equal to 7/5, C(1,2/5) is not a solution to the equation.
D(2,2 2/5):
When x = 2 and y = 2 2/5, we have:
2 2/5 = 2 + 2/5
2 2/5 = 2 2/5
Since 2 2/5 is equal to 2 2/5, D(2,2 2/5) is a solution to the equation.
Therefore, the ordered pairs B(-1,2/5) and D(2,2 2/5) are the solutions of the equation y = x + 2/5.
