## How do you find the slope of a line with two given points?

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values.

## What does it mean if the slope of a line is zero?

This relationship always holds: a slope of zero means that the line is horizontal, and a horizontal line means you’ll get a slope of zero. (By the way, all horizontal lines are of the form “y = some number”, and the equation “y = some number” always graphs as a horizontal line.)

## What does a positive slope look like?

What the Slope Means. A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.

## What is the point of standard form of a line?

The standard form of a line is just another way of writing the equation of a line. It gives all of the same information as the slope-intercept form that we learned about on Day 5 just written differently.

## Why do we use standard form?

Standard form is used all the time in science and engineering. It allows you to comprehend numbers with extreme sizes such as the diameter of the sun or the diameter of an atom.

## What is standard form in elementary math?

standard form is the usual way of writing numbers in decimal notation, i.e. standard form = 876, expanded form = 800 + 70 + 6, written form = eight hundred seventy six.

## What are the 3 rules for writing numbers in standard form?

Small numbers can also be written in standard form. However, instead of the index being positive (in the above example, the index was 3), it will be negative. The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number).

## What is the standard form of 12345?

The standard form of the number 12345 is equal to “1.2345 × “.

## What is the standard form of 200000?

200000 in the standard form written as 2 × 10 5 .
