Your equation is currently in a form called the slope-intercept form of linear equations. Its called that simply because it tells you those two pieces of information immediately! The standard form is:
y = mx + b
Where m is the slope and b is the y-intercept. Thus, it is easy enough to see that m is 6 and b is -6. Therefore,
Slope: 6
Y-Intercept: -8

The slope refers to the distance the line will rise and run(left or right). The y intercept is the point where the line crosses the y axis. When the equation is in the form y = mx + b the rise is the m value and the y intercept is b.
In your problem the slope is 6 (or 6/1) If you graph this equation the line will rise 6 units for every one unit right. The y intercept is -8 so the line will cross the y axis at -8.

Well, the form of that equation is y=mx+b. "M" is the slope" and "b" is the y-intercept. So, y=6x-8 means that the slope is positive 6 and the y-intercept is -8. If you learned this in school, I suggest you pay closer attention, ask a teacher, or call a fellow classmate for help. Good luck and I hope this helps! ;-)

slope formula... y=mx+b
where m is slope, and b is y intercept
m=6, therefore slope is 6... or better, 6/1... meaning slope goes up (y direction) 6 units and across (x direction) 1 unit
and y intercept = b which in this case = -8
so the 6 to 1 slope crosses the y axis at -8 and goes off in both directions from there up 6, across 1... up 6 more, across 1 more, etc.
it also does this on the other side of the y axis... down 6 and across one...etc.

slope = 6 (coefficient of x)
y intercept = -8

to find the slope, you can use two methods. First you could sub in two different values for x to get two different y values (two points), and you could use the equation for slope (y1 - y2) / (x1 -x2) to find slope or you could also manipulate the given equation to the form f y = m(x + b) where m is the slope.
to find the intercept, you simply set x = 0 and solve for y. remember that an interceptor is a point and therefore should be written in the form (x, y)

slope is 6
y intercept is -8
When you have an equation in the form y = mx +b, m is always the slope and b is always the y intercept.
