unless the line is vertical or horizontal, it extends left-right and up-down forever.
So, the domain and range are both (-∞,+∞)
the slope of Ax+By=C is -A/B
for the x-intercept, set y=0
for the y-intercept, set x=0
for example the intercepts of 3x+4y=8 are (0,2) and (8/3,0)
for 3x-4y > 16
the solution set is all the shaded area below the line 3x-4y=16.
Graph the two lines
2x + 3y = 18
3x -4y > 16.
Give the Domain and Range, Slope, and Y-intercept for each line.
Graph each equation above on the graph below and show all work. Give the Domain and Range, Slope, and Y-intercept for each line. Explain in detail how you got each answer.
2x + 3y = 18 3x -4y > 16

Thx so much Steve. I think I still need a little help tho.
