Identify the linear equation.
Responses
A y = lxl + 5y = lxl + 5
B y = 12
x + 3y = 1 2 x + 3
C y = x2
- 4y = x 2 - 4
D y = 34
x2
The linear equation is B) y = 12.
The linear equation is:
B) y = 12x + 3
The linear equation can be identified by looking for the equation that represents a straight line.
In this case, option B, "y = 12x + 3," is the linear equation. This is because it is written in the standard form of a linear equation, y = mx + b, where m represents the slope of the line and b represents the y-intercept.
To check if an equation is linear, you can also look for the absence of any exponents other than 1 on variables or terms. Option A has the variable x raised to the power of 2, so it is not a linear equation. Option C has the variable y raised to the power of 2, so it is also not a linear equation. Option D does not have a variable with an exponent, but it does not follow the standard form of a linear equation, so it is not linear either.
