Question

Select all of the linear equations that are in standard form. Group of answer choices 15x-14y=22 3x+5y=7 2.5x-y=17 -2x+8y=14 42x+0.4y=15

Answer 1

Answer: 15x-14y=22

3x+5y=7

2.5x-y=17

42x+0.4y=15

Explanation:

The standard linear equation of two variables x and y is given by :-

Ax +By = C , where A is a positive integers, and B, and C are integers.

Therefore, from the given options the linear equations that are in standard form are

15x-14y=22

3x+5y=7

2.5x-y=17

42x+0.4y=15

[-2x+8y=14 is not in standard form ∵ -2 is a negative integer.]
