How do i graph y=7/2x-2

The simple way:

-- Pick any number.  Write it in place of 'x'.
-- Calculate the value of 'y'. (It's 7/2 of your number, minus 2)
-- Now you have one (x, y) point.  Mark a dot at that point on the graph.

-- Pick another number.  Write it in place of 'x'.
-- Calculate the value of 'y'. (It's 7/2 of your number, minus 2)
-- Now you have another (x, y) point.  Mark a dot at that point on the graph.

-- Lay the edge of your ruler along the two dots on the graph.
-- Draw a straight line along the edge of the ruler, as far as you want
in each direction.



The better way:

-- Look at the equation. Find the y-intercept of the graph.  It's -2 .
-- Mark a dot on the y-axis at  y=-2.

-- Look at the equation again.  Find the slope of the graph.  It's 7/2.
-- Draw a straight line with a slope of 7/2 through the dot on the y-axis.
