How to write the equation of a line given two points using slope intercept method

The video tutorial explains how to find the slope between two points and how to write the equation of a line using the slope-intercept method. It covers the steps to calculate the slope, find the Y-intercept, and solve for B in the line equation. The tutorial emphasizes the importance of understanding the slope and Y-intercept to write a line equation effectively.

What is the first step in finding the slope between two points?

• Identify the y-intercept

• Use the point-slope formula

• Plug the points into the standard slope formula

• Find the midpoint of the points

Which formula is used to write the equation of a line in slope-intercept form?

• Y = M + B

• Y = M(X - X1) + Y1

• Y = X + B

• Y = MX + B

What is the value of the slope (M) in the example provided?

• 3

• 2

• 1

• 0

How do you determine the y-intercept (B) once you have the slope?

• By using the distance formula

• By using the midpoint formula

• By substituting a point into the equation

• By finding the average of the x-values

What is the final equation of the line in the example?

• Y = 2X - 8

• Y = 2X + 8

• Y = -2X + 8

• Y = -2X - 8
