Solve:
y=2x+1
-2x+y=1

x=3 and y=4

Step-by-step explanation:

all real numbers

x = 0

y = 1

Step-by-step explanation:

-2x + y = 1

-2x + (2x + 1) = 1

-2x + 2x + 1 = 1

x + 1 = 1

x = 0

y = 2x + 1

y = 2(0) + 1

y = 0 + 1

y = 1

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
