Solve by finding y and graph using the slope and y-intercept:

3x-y=1(My answer -y=3x+1)which is wrong

could not graph it.

x-y=3 (My Answer y=x-3) which is wrong

could not graph it

3x-8=y(My Answer -6x+2y=-16)

graph (0,8) (1,5) which is wrong

Use the point-slope 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)

y = 3x - 1

x-y = 3

y = x - 3

3x-8 = y

y = 3x - 8

in each case, y=mx+b where m is the slope and b is the y-intercept.

now that you have the y-intercept, the x-intercept is where y=0

On the first one,

y = 3x-1

0 = 3x-1

x = 1/3

so, plot (0,-1) and (1/3,0) and draw a line between them.

Similarly for the others. just get the x-intercept and draw a line between the intercepts.
