Graphing this is easier than you think, the equation is already in slope intercept form,
when you start graphing your first gonna try and find the y intercept (b)
[tex]f(x) = m(x) + b[/tex]
lets take excersise 17 for example,
y-intercept is -4, now go to your graph and place the first dot over -4, after that you find the slope, in the equation the slope is m(x) in this case it's 1/2, since its a fraction here's what you do,
Start of from your y-intercept (-4) them if the slope is a fraction you will go from -4 up or down( if the numerator is positive you move upwards, if it's negative you move down words), then from there you love left or right(if the denominater is positive you move right, if it's negative you move left, then draw a line from the y-intercept to the las dot you moved.
