How do graph the line 9x equals y - 4?

Answer 1

5

Answer 2

To graph the line 9x = y - 4 set up a table where on one side you have values for x and on the other you have values for y Set x to a range of values and calculate y (start with fairly obvious values like 0 and 1 and -1 continue with some extreme values like 100 and -100): x y

0 4

1 13

-1 -5

100 904

-100 -896 enter some of these value onto your graph paper (you could ignore the extremes they are very far out) You see that you get a line that is fairly steep (tat comes from the 9 as x factor) and the line crosses the x axis at 4 (that comes from the y-4) Answer: As the equation is that of a straight line, you only need to calculate the values of two points. The easiest are when x=0 (and y= 4) and when y=0 (and x=-(4/9))
