How to write an equation given two points using point slope formula - coolmath

The video tutorial explains how to find a linear equation given two points. It covers two methods: the slope-intercept method and the point-slope method, focusing on the latter. The tutorial demonstrates how to calculate the slope using the formula (Y2 - Y1) / (X2 - X1) and how to find the Y-intercept by substituting one of the points into the equation. The final linear equation is derived by combining the slope and Y-intercept.

What are the two methods mentioned for finding a linear equation from two points?

• Polynomial and rational methods

• Exponential and logarithmic methods

• Quadratic and cubic methods

• Slope-intercept and point-slope methods

In the point-slope form, what does 'm' represent?

• The y-intercept

• The slope

• The x-intercept

• The midpoint

How is the slope calculated using two points?

• By adding the x-coordinates

• By subtracting the y-coordinates and dividing by the difference in x-coordinates

• By multiplying the x and y coordinates

• By adding the y-coordinates

What is the next step after finding the slope in forming a linear equation?

• Finding the y-intercept

• Finding the x-intercept

• Calculating the midpoint

• Determining the axis of symmetry

Which point is typically chosen to find the y-intercept when using the point-slope form?

• Any point, but usually one with positive coordinates

• The point with the largest y-coordinate

• The point with the smallest x-coordinate

• The midpoint of the two points
