It is called as the slope intercept form. For two coordinates, x 1 ,y 1 and x 2 , y 2 , the slope of a line is the ratio of difference between the difference between the y coordinates and the difference between x coordinates, also known as the rise over the run. Here 'm' is the slope of the line and 'b' is the point at which the line intercepts the y - axis.
A line for which the slope in negative is said to move from left to right in a graph. The slope of a line is found by the ration of difference in y-coordinates to the difference in x-coordinates. If this value is negative for a line, then the line has a negative slope. The direction of a line is described by its slope. The slope can be positive or negative, based on its direction. The root is also the progenitor of sleeve the arm slips into it and, by dropping the s in front we get lubricate and lubricious a word describing a person who is "slick", or even "slimy".
Many variations of where the idea of M for slope originated seem to be mostly myth. One of the most common is that the letter was used by Descarte because it was the first letter of some French word or another that related. I inquired, and she said because of the "American" word "slope. A linear equation an equation with highest power on variable as 1 , graphically represents a straight line on 2-D plane graph. AJ Speller. Oct 7, This is a linear equation. A linear equation is the representation of straight line.
The slope tells me that, for every second that passes, the speed of the ball decreases by 32 feet per second. Also, by the way, the velocity will eventually become zero when the ball reaches the peak of its arc , and will then become negative when gravity takes over and pulls the ball back down to the ground.
The exercise defines v as measuring the velocity of the ball. The intercept value tells me that, when the ball was released, it was launched upward at a speed of feet per second. This value tells me that, for every increase by 1 in my input variable x , I get an increase of 9. The slope tells me that, fo every increase in the pollution index by one unit say, from a pollution index of 6 to a pollution index of 7 , there are nine or ten more fish deaths during the year.
Why "or"? Because the 0. The number of fish found will be a whole number; in this case, that whole number is expected to be either nine or else ten. The intercept value tells me that, even if the index were zero that is, even if the water were utterly pure , there would still be about fish deaths a year anyway. Word problems with linear equations that is, with straight-line models almost always work this way: the slope is the rate of change, and the y -intercept is the starting value.
