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

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.
