I would greatly appreciate it if someone would please be kind enough to take the time and show me how to work these problems. Thank you very much
Solve by finding y and graph using the slope and yintercept:
3xy=1(My answer y=3x+1)which is wrong
could not graph it.
xy=3 (My Answer y=x3) which is wrong
could not graph it
3x8=y(My Answer 6x+2y=16)
graph (0,8) (1,5) which is wrong
Use the pointslope from of an equation to write the following in slope intercept form:
m= 3/8 point: (3,5) (I did not try this one at all)

3xy = 1
y = 3x  1
xy = 3
y = x  3
3x8 = y
y = 3x  8
in each case, y=mx+b where m is the slope and b is the yintercept.
now that you have the yintercept, the xintercept is where y=0
On the first one,
y = 3x1
0 = 3x1
x = 1/3
so, plot (0,1) and (1/3,0) and draw a line between them.
Similarly for the others. just get the xintercept and draw a line between the intercepts.
