Which of the following equations represents a linear function? a-y=√x + 1 b-y=1/x c-y=x^2 +4 d-y = -2/3x + 4/3 marking brainlest

A linear equation has maximum power of a variable(variables) 1.

In order to find the linear equations we need to check the equations with variable with power one.

Also the variable should be in numerator only.

Let us check option one by one:

a-y=√x + 1 we have a radical on x.

Therefore, it's not a linear equation.

b-y=1/x

We have x in the denominator of 1.

Therefore, it's not a linear equation.

c-y=x^2 +4

We have power 2 of x. Therefore, it's not a linear equation.

d-y = -2/3x + 4/3.

We have x and y powers only 1.

Therefore, it's the only linear equation.

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
