Answer:
A & B
Step-by-step explanation:
5x - 2y = 10 (1)
-2.5x + y = -5 (2)
When you multiply (2) by -2, you get (1), so there can be many solutions
To choose from the given options, plug in the values to check which ones satisfy the equation
5x - 2y = 10
A) (2,0)
5(2) - 2(0) = 10
10 = 10 (true statement)
B) (-2,-10)
5(-2) - 2(-10) = 10
-10 + 20 = 10
10 = 10 (true statement)
Answer:
y = x + 1
Step-by-step explanation:
y = -3x + 5
Let y = 2
2 = -3x +5
-3 = -3x
x = 1
(1, 2)
y = mx + b
y = 1x + b
2 = 1 + b
b = 1
Therefor, the other one is, y = x + 1
