Find the linear equation given two points

The video tutorial explains how to find the equation of a line given two points. It starts with an introduction to the slope-intercept form, Y = MX + B, where M is the slope and B is the Y-intercept. The teacher demonstrates how to use the slope formula, M = (Y2 - Y1) / (X2 - X1), by labeling coordinates and calculating the slope. Finally, the tutorial shows how to identify the Y-intercept from the given points, concluding with the complete line equation.

What does the 'M' represent in the slope-intercept form equation Y = MX + B?

• The constant term

• The Y-intercept

• The X-intercept

• The slope

Which formula is used to calculate the slope between two points?

• M = (X1 - X2) / (Y1 - Y2)

• M = (Y1 - Y2) / (X1 - X2)

• M = (Y2 - Y1) / (X2 - X1)

• M = (X2 - X1) / (Y2 - Y1)

If you have points (0, 3) and (2, 7), what is the slope of the line?

• 1

• 4

• 2

• 3

How can you identify the Y-intercept from a set of points?

• By calculating the average of all Y-coordinates

• By finding the point where the Y-coordinate is zero

• By calculating the average of all X-coordinates

• By finding the point where the X-coordinate is zero

Given the point (0, 3), what is the Y-intercept of the line?

• 1

• 0

• 3

• 2
