Well, honey, turning a negative y into a positive y in slope is as easy as flipping a pancake. All you gotta do is multiply the entire equation by -1, and voila, your negative y becomes a positive y. Just remember, math may not always be a piece of cake, but with a little attitude and some basic algebra, you can conquer anything.
You know when the slope of a line is negative when m in the slope-intercept form equation y=mx+b is negative. For example, y=-3x+2 has a negative slope since m (which is -3 in this case) is negative. This is the same when finding a positive slope, because if m is positive, then the slope is positive.
If you mean: y = 12x+1 then it has a positive slope of 12 and a y intercept of 1
Yes, there a relationship between the sign (positive or negative) of the slope of a line and the angle the line makes with the x-axisWhen a line slopes up from left to right, it has a positive slope. This means that a positive change in y is associated with a positive change in x. The steeper the slope the greater the rate of change in y in relation to the change in x.When a line slopes down from left to right, it has a negative slope. This means that a negative change in y is associated with a positive change in x.
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
... negative.... negative.... negative.... negative.
The answer depends on the signs of the original intercepts.x negative, y negative: negative slope becomes less negative and could go positive.x negative, y positive: positive slope becomes greater.x positive, y negative: positive slope becomes less positive and could go negative.x positive, y positive: negative slope becomes more negative.For 1 and 3, the slope changes sign when the y intercept crosses the origin.

If you mean: y = 2x+3 then it is a positive slope of 2 with a y intercept of 3
If you mean: y = 12x+1 then it has a positive slope of 12 and a y intercept of 1

y=mx+b is the slope intercept equation m=slope b= y-intercept y=-7x + 2 m= -7 b= +2
If the slope is negative, or going downhill, then that means the graph will be a regular coordinate system (x and y axis). The only thing that is different is the direnction of the slope. A positive, or regular, slope formula, looks like this: y= 2x + 3, for example. Since there are no negative signs, the slope would be going upwards. But a negative slope, like you are talking about, would look either like this: y= -2x + 3 ( negative sign in front of 2 ). Remember: If the equation looks like this: y= 2x - 3, it would still be positive, because it is behind the 2x. Good luck!

When the slope of a line reaches zero it then will be parallel to the x or y axes depending if its a positive or a negative slope.
