Algebra graph

1.) which quadrant or axis would this lie in?

X+2Y=1:(0, ? ), (-2, ? ), (2, ? )

2.) what is the slope and y intercept for this?

y= -x+5

3.) what would this look like on a graph?

x=9

4.) What is the equation if it is written in standard form using only intergers as the coefficients?

the line through ( -2,4 ) that is perpendicular to the X-axis

5.)
how do you graph these two inequalities?

a) Y< 1/2X+2

B) X-3Y<9

1.) which quadrant or axis would this lie in?

X+2Y=1:(0, ? ), (-2, ? ), (2, ? )

0 + 2Y = 1
Y = 0.5

Answer: (0, 0.5) lies on the y-axis.

-2 + 2Y = 1
Y = 1.50

Answer: (-2, 1.50) lies in quadrant II.

2 + 2Y = 1
Y = -0.5

Answer: (2, ...
