Answer:
the function y – 2 = –5(x – 2) is linear.
Step-by-step explanation:
We need to find the correct option from provided options which represents a linear function
Since, the linear equation is in the form of <u>y=mx+c </u>where m is slope of line.
In first part y – 2 = –5(x – 2)
Simplify, the function
Add both the sides by 2, in above equation
This function is in the form of y=mx+c
so, this is a linear function
In second part x + 7 = –4(x + 8)
Simplify, the function
subtract both the sides by 7, in above expression
add both the sides by 4x,
divide both the sides by 5,
This is not in the form of y=mx+c
so, this is not a linear function
In third part y – 3 = y(x + 4)
Simplify, the function
add both the sides by 3,
This is not in the form of y=mx+c
so, this is not a linear function
In fourth part y + 9 = x(x - 1)
Simplify, the function
subtract both the sides by 9,
This is not in the form of y=mx+c
so, this is not a linear function
Therefore, the function y – 2 = –5(x – 2) is linear.
