WILL GIVE BRAINLIEST! Which of the following equations are linear equations in two variables? (Select all that apply.)

y2 = x − 8

y = −x2 + 7

x − 9y = 4

y = −3x + 5

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
