## When would you use point slope form instead of slope-intercept?

If given the slope and a point, use the point-slope form. If given the slope and the y-intercept, use the slope-intercept form.

**What is point slope-intercept form?**

Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). Watch this video to learn more about it and see some examples. Created by Sal Khan.

### How do you find slope given two 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. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

**What is the difference between point slope form and slope intercept form?**

What is the difference between point slope form and slope intercept form? Point slope will tell you two things by looking at the equation (and doing no work) a point on the line, and the slope of the line. Slope-intercept will tell you two things also, the y-intercept (if it has one), and the slope.

#### What is the slope of a straight line?

the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y- intercept (that is, the point where the line crosses the vertical y-axis). For a line, its slope and intercept are two important parameters to determine its look and location.

**How to convert x to point slope form?**

Convert to point slope form. Substitute a convenient value of x into your equation and solve for y (You’re doing this to get the point x 1 ,y 1 ). Let’s choose x=5. Yes, you could choose x=0 and make your life really easy! Remember you only need to choose one x value, I chose two different values …but you could have chosen any value at all for x.
