Answer:
5+2y=13 is linear
y=+7 is linear
y-5=2(x-1) is linear
=x+7 idk this is not complete so i cant answer it
x=-4 is linear
HOPE IT HELPED<3 tell me if I am wrong.
Step-by-step explanation:
The equations 5 + 2y=13, y – 5 = 2(x – 1), y/2 = x + 7 and x=-4 represent linear relationships.
The given equations are 5 + 2y=13, y = 1/2x²+7, y – 5 = 2(x – 1), y/2 = x + 7 and x = –4.
We need to select all of the equations that represent linear relationships.
A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax+B= 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant.
Now, in the equation 5 + 2y=13 the highest power of the variable is 1.
In the equation y = 1/2x²+7 the highest power of the variable is 2.
In the equation y – 5 = 2(x – 1) the highest power of the variable is 1.
In the equation y/2 = x + 7⇒y=2x+14 the highest power of the variable is 1.
In the equation x=-4, the highest power of the variable is 1.
Therefore, the equations 5 + 2y=13, y – 5 = 2(x – 1), y/2 = x + 7 and x=-4 represent linear relationships.
