Answer:
y = 8 is your answer.
Step-by-step explanation:
-1 is x and you have the equation.
y = -x + 7
y = -(-1) + 7
y = 8 is your answer.
Answer: The required value of y is 8.
Step-by-step explanation: We are given the following linear rule :
[tex]y=-x+7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We are given to find the value of y if the point (-1, y) lies on the graph of (i).
We know that
if the point (-1, y) lies on the graph of equation (i), then it must satisfy the equation.
Therefore, from equation (i), we get
[tex]y=-x+7\\\\\Rightarrow y=-(-1)+7\\\\\Rightarrow y=1+7\\\\\Rightarrow y=8.[/tex]
Thus, the required value of y is 8.
