• -10x+10y+60

• -10y+10x-60

• 10y+10x-60

• -10x+10y+60

6x/3x + 0(9) -7y(2)

• 2x-|4y

• 2z-14y

• 2x-14y

• 2x+14y

3/4h=-45/52

• h=-15/23

• h=-15/-13

• h=-15*13

• h=-15/13

3x+4(x-8)-x=3/5(10x+15)

find x

• infinitely many solutions

• found it, it's in the question

• 52

• no solution

A line perpendicular to 4x-y=12 that passes through (8,2).

• y=1/4x-4

• y=-1/4x+4

• -y=-1/4x+4

• y=1/4x+4

1/x + 1/y = 2/3

Is it linear? If it is write the equation in standard form.

• No

• Yes

  x-y=2/3

• yEs

  x+y=-2/3

• YeSs

  -x-y=2/3

A line passing through (5,3) that is parallel to the line 9x + 3y = 6

• what is parallel?

• y=-3x+18

• y=3x+18

• x=-3x+18

Solve the inequality

7+z<3

• z>-4

• -4<z

• z<-4

• z<4

Solve the inequality

5(p+2)-2(p-1) > 7p + 4

• p<2

• why would you do this to me?

• p<-2

• p=2

x+y=1

• (2,0)

• (1.0)

• (0,1)

• (1,0)
