# Is M the slope?

## Is M the slope?

In the equation y = mx + b for a straight line, the number m is called the slope of the line.

### Who first discovered slope?

Renee Descartes was the person that invented slope of a line. This all began in France where he invented slope of a line. Other mathematics say Renee Descartes is acknowledged as the discover of the formula (1595-1650) though there are little write ups on this formula.

**What does a slope of infinity look like?**

An infinite slope is simply a vertical line. When you plot it on a line graph, an infinite slope is any line which runs parallel to the y-axis. You can also describe this as any line that doesn’t move along the x-axis but stays fixed at one constant x-axis coordinate, making the change along the x-axis 0.

**What is a slope in math?**

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as “rise over run” (change in y divided by change in x).

## What is slope in math in real life?

Slope is a measure of steepness. Some real life examples of slope include: in building roads one must figure out how steep the road will be. skiers/snowboarders need to consider the slopes of hills in order to judge the dangers, speeds, etc.

### What is slope 7th grade?

Standard: 7th grade, Algebra & Functions 3.3, Graph linear functions, noting the vertical change. (change in y-value) per unit of horizontal change (change in x-value) is always the same and know the ratio (“rise over run”) is called the slope of a graph.

**Who invented slope?**

**Why is the slope called M?**

It is not known why the letter m was chosen for slope; the choice may have been arbitrary. John Conway has suggested m could stand for “modulus of slope.” One high school algebra textbook says the reason for m is unknown, but remarks that it is interesting that the French word for “to climb” is monter.
