5=-10x+5y (-2,1)

Question

5=-10x+5y (-2,1)

a. y=2x+1

b.y=2x+b

c.y=-2x+b

d.y=2x+5

Answer 1

5= -10x+5y

Rearrange the equation

-10x+5y=5

Add 10x on both sides

-10x+10x+ 5y=10x+5

5y= 10x+5

Divide both sides by 5

5y/5 =10x/5+5/5

y=2x+1

Answer:- a

Answer 2

Divide both sides by 5,

1 = -2x + y

Add -2x to both sides,

2x+1 = y

By the property of symmetry,

y = 2x+1

Answer: a.
