Question

10. Which of the following is a linear equation?

a. 4x² +9y2 = 25
b. 2+ 6 = 15
C. 2x-3y=7
d. 4x+6 = 30​

Answer 1

C.

Explanation:

It is linear because it have two variables (x and y) and the highest powers that they are raised to are 1

Answer 2

For this case we have that by definition, a linear equation is of the form:

`ax + b = 0`

That is, the largest exponent of the variable is 1.

Then, according to the options given, we have that the correct option is option D, that is:

`4x + 6 = 30`

Answer:

Option D
