So 9x plus 54

54 plus 7 is 61

So y equals 9x plus 61. is it correct?

**Reiny**, Tuesday, September 29, 2009 at 8:39amnow that you have y = 9x + 61 , your question was to graph it.

so you need any two points.

One obvious point is the y-intercept or (0,61) but that's hard to plot.

So using some number sense, we pick negative x's to bring the y down to a reasonable value

say x = -7, then y = -2

or let x = -8, then y = -11

one more try,

let x = -6, then y = 7

so now you have 3 points, (-7,-2), (-8,-11), and (-6,7)

plot any two points, join them and use the third point as a check-point.
