Determine whether the equations are parallel,perpendicular or neither
Slope of line 9x + 3y = 12 is -3.Slope of line 7y-31=21x is 3.
The slopes of lines are not equal and product of slopes is not -1 so lines are neither parallel nor perpendicular.
Slope of line y=4x-3 is 4.Slope of line 12x+3y=7 is -4.
Graph this linear inequality2x+y <= 2
Please don't forget to click ACCEPT. BONUS is always appreciated.
Graph this linear equality should read less than or equal to not equal to. My error.
Also,can you help me with these problems:
Choose the ordered pair which is a solution of the inequality
1)2x+3y less than or equal to 0
2) 2x-4y less than or equal to 6
For 1) I have (-1,1)
For 2) I have (3,-1)
Are these answers correct? These are the 2 last questions I asked for help with.
1) Choose the ordered pair which is a solution of the inequality
2x+3y less than or equal to 0
2) Choose the ordered pair which is a solution of the inequality
2x-4y less than or equal to 6
