Find the equation of a line through two points using slope intercept form

The video tutorial explains how to find the equation of a line given two points. It covers the formula Y = MX + B, where M is the slope and B is the Y-intercept. The tutorial guides through calculating the slope using the slope formula and labeling coordinates. It also demonstrates finding the Y-intercept by choosing a point and solving for B. Finally, it combines the slope and Y-intercept to form the line equation.

What is the general form of the equation of a line?

• Y = MX + B

• Y = AX + C

• Y = BX + D

• Y = CX + E

What is the formula for calculating the slope between two points?

• M = (X1 - X2) / (Y1 - Y2)

• M = (Y2 - Y1) / (X2 - X1)

• M = (Y1 - Y2) / (X1 - X2)

• M = (X2 - X1) / (Y2 - Y1)

Why is it important to label points as X1, Y1, X2, Y2?

• To make the equation easier to solve

• To ensure the points are in the correct order

• To avoid confusion when calculating the slope

• To make the graph look neat

What happens when you subtract a negative number from another number?

• The operation becomes addition

• The result is always zero

• The result is always negative

• The result is always positive

After finding the slope, what is the next step in forming the equation of a line?

• Calculate the midpoint

• Choose a point and solve for the y-intercept

• Find another point on the line

• Graph the line

What is the y-intercept in the equation Y = 2X + B if B is found to be 11?

• 5

• 11

• 2

• 0

Which point is preferable to choose when solving for the y-intercept?

• The point closest to the origin

• The point with the least negatives

• The point farthest from the origin

• The point with the most negatives
