Y = 3x − 8
Nana76 [90]

Answer:

A. You would first plot the y intercept.  The first equation would be (0,-8) and the second equation is (0,-11).  Then you would plot the slope.  For the first equation, from (0,-8), you would move up 3 plots and right 1 plot.  For the second equation, from (0,-11), you would move up 9 plots and right 1 plot.

B. The solution to the pair of inequalities is (1/2, -13/2).  That is the intersection and point of the two lines.  You would need to graph the two lines (see part A answer) and then find the intersection.  

Hope this helps!

-5x+2y=6
2y=6+5x
y=5/2x + 6

x+3y=3
3y=3-x
y=-x/3+1

-2x+y=4
y=2x+4

4x+9y=-9
9y=-4x-9
y=-4/9x+1

Hope this helps.
