It means that if you go from left to right, on the graph, the slope - while remaining positive - decreases.In math terms: the first derivative is positive, but the second derivative is negative. Or more informally: from left to right, the curve goes up; on the other hand, it is concave downwards.
It means that the variable in question is increasing, but the rate at which it is increasing is slowing down.
The following example may help illustrate this. Consider a car which starts from a standstill and gets up to its top speed as quickly as it can (ignore gear changes). At first it goes faster and its speed increases very quickly. The slope is a very large positive number. After a while, though, that sort of acceleration cannot be maintained and, although the speed is still increasing (the slope is positive ...) it is now increasing much more slowly (... but it is less positive than before). Eventually, the car reaches its top speed and the car cannot accelerate any further. The slope is now zero.
If you mean: y = 2x+3 then it is a positive slope of 2 with a y intercept of 3
If a line has a negative slope it is going 'down hill' and if it has a positive slope it is going 'up hill'
Do you mean y = -8x+20 Then if so the perpendicular slope is positive 1/8.
X=5 is a vertical line, so it has no slope. When I say it has no slope, I don't mean the slope is 0, I mean the slope is nonexistent.
If you mean y = 11x then the slope is 11
If you mean: y = 12x+1 then it has a positive slope of 12 and a y intercept of 1
If you mean: y = 2x+3 then it is a positive slope of 2 with a y intercept of 3
If a line has a negative slope it is going 'down hill' and if it has a positive slope it is going 'up hill'
The slope can be remembered as "rise over run". When the slope is an integer, it means that the rise over run is positive.
Acceleration
Assuming position is on the y axis and time is on the x axis, a positive slope means the position has increased over time.
Assuming you mean the slope of a line, not the scope, the slope of a line is determined by its rise over its run. Take 2 points on the line (x1,y1), (x2,y2) and find the slope by plugging it into this equation: (x1-x2)/(y1-y2). If the answer is positive, the slope is positive, if the answer is negative, the slope is negative, if the answer is zero, the slope is zero, and if the answer is undefined (i.e. dividing by zero), your slope is undeifined.
Do you mean y = -8x+20 Then if so the perpendicular slope is positive 1/8.
X=5 is a vertical line, so it has no slope. When I say it has no slope, I don't mean the slope is 0, I mean the slope is nonexistent.
What does it mean if a slope is numerically a higher value than another slope
If you mean y = 2x+1 then it is a straight line equation whereas the slope is 2 and the y intercept is 1
The formula y=Mx + B is the slope intercept equation of a line. If you where to graph this on a 2 dimensional graph with x and y axes the number represented by M would be the slope of the line. A positive value of M would mean a positive slope and the line will rise as one views it from left to right. A negative value of M would indicate a negative slope and the line will descend as one views it from left to right. A value of zero for M would indicate a horizontal line.
