You now know half of each answer. If x = 0, substitute that in to the equation. y=5(0)-9 ….. y=0-9 ….. y=-9

So when x=0, y=-9. The y-intercept is (0, -9).

If y = 0, same procedure but different variable is substituted.

0=5x-9 ….. 9 = 5x ….. (9/5) = x

So when y=0, x=(9/5). The x-intercept is (9/5, 0).

Hope that helps!

the slope-intercept form:

y = mx+b

where the y intercept is b

and the slope is m

your problem: y=5x-9

has a slope of 5 and a y intercept of -9

m=5, b=-9

now that you know this, you can graph the line and find out what the x intercept is.

graph: start a -9 on the y axis. now use the slope of 5

which is the same as 5/1

go 1 to the right and 5 up, make a point there, then go 1 to the right and 5 up, another point there and so on.

hope this helps.
