Writing the equation from a graph

The video tutorial explains how to derive the equation of a graph in the form Y = MX + B. It covers identifying the Y intercept, which is where the graph crosses the Y axis, and calculating the slope using a slope triangle. The tutorial concludes with writing the final equation using the determined slope and Y intercept.

What is the general form of a linear equation?

• Y = AX^2 + BX + C

• Y = X^2 + Y^2

• Y = A/B

• Y = MX + B

Where does the Y-intercept of a graph occur?

• At the highest point of the graph

• At the origin

• Where the graph crosses the Y-axis

• Where the graph crosses the X-axis

In the given example, what is the Y-intercept value?

• 0

• 3

• 1

• 2

How do you calculate the slope of a graph?

• By dividing the change in Y by the change in X

• By finding the change in X values

• By adding the change in X and Y values

• By finding the change in Y values

What is the slope of the graph in the example?

• -3

• 3

• -2

• 2
