## How do you find an equation with two points?

**Equation from 2 points using Slope Intercept Form**

- Calculate the slope from 2 points.
- Substitute either point into the equation. You can use either (3,7) or (5,11)
- Solve for b, which is the y-intercept of the line.
- Substitute b, -1, into the equation from step 2.

## How do you find the slope from two points on a graph?

## How do you find slope without points?

Caldwell Math slope of a line given a graph and no points flip.MP4

## How do I find slope and y intercept?

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y.

## How do you find a perpendicular slope?

## How do I find slope?

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

## What is the formula to find the slope?

**There are three steps in calculating the slope of a straight line when you are not given its equation.**

- Step One: Identify two points on the line.
- Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
- Step Three: Use the slope equation to calculate slope.
