Answer:
(x, y) = (1, 4)
Step-by-step explanation:
Given: x+y=5 and 2x-y=-2
Solve for y and x
x+y=5; solve for y
y = 5 - x; substitute into other equation
2x-y= -2
2x - (5 - x) = -2
2x - 5 + x = -2; combine x's
3x - 5 = -2; add 5 to both sides
3x =3; divide by 3
x = 1; use this to solve for y
x+y=5
1 + y = 5; subtract 1 from both sides
y = 4
(x, y) = (1, 4)
Step-by-step explanation:
It's the equation of a line.
We need only two points to the plotting a graph of a line.
y = -x - 3
for x = -3
y = -(-3) - 3 = 3 - 3 = 0 → (-3, 0)
for x = 0
y = -0 - 3 = 0 - 3 = -3 → (0, -3)
