To solve such problems we need to know about the Linear function.
<h2 /><h2>Given to us</h2>A.) y – 2 = –5(x – 2)
B.) x + 7 = –4(x + 8)
C.) y – 3 = y(x + 4)
D.) y + 9 = x(x – 1)
<h2>Linear function</h2>A linear function is a function that is in the form of y=mx+c. thus we will check which functions are in this form, to know that a function is linear or not.
A.) y – 2 = –5(x – 2)
As we can that the function is in the form of y=mx+c. therefore, the function is a linear function.
B.) x + 7 = –4(x + 8)
As we can that the function is not in the form of y=mx+c. therefore, the function is a non-linear function.
C.) y – 3 = y(x + 4)
As we can that the function is not in the form of y=mx+c. therefore, the function is a non-linear function.
D.) y + 9 = x(x – 1)
As we can that the function is not in the form of y=mx+c. therefore, the function is a non-linear function.
