How do I do the question -x+y=4 need help please and thank u

y= x+4: x= y-4

Step-by-step explanation

you have to do the inverse of whatever you figuring out so to solve for Y you would add x to both sides and once you have Y alone that's your answer and for X you subtract Y and divided both sides by -1 because lone variable can never me negative.

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
