Write the equation of a line from given graph

The video tutorial explains how to convert an equation into slope-intercept form (Y=MX+B). It covers identifying the Y-intercept and calculating the slope by examining changes in Y and X values. The tutorial guides students through writing the equation using the slope and Y-intercept, emphasizing the importance of understanding these components for graphing linear equations.

What is the Y-intercept of a graph?

• The point where the graph crosses the X-axis

• The point where the graph crosses the Y-axis

• The slope of the graph

• The highest point on the graph

How is the slope of a line calculated?

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

• By multiplying the X and Y values

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

• By adding the X and Y values

What does the 'M' represent in the equation Y = MX + B?

• The Y-intercept

• The slope

• The constant term

• The X-intercept

If a line has a slope of -4/7 and a Y-intercept of 4, what is the equation of the line?

• Y = 4X - 7

• Y = -4/7X + 4

• Y = 4/7X - 4

• Y = 7X - 4

What is the first step in writing the equation of a line in slope-intercept form?

• Calculate the midpoint

• Identify the highest point on the graph

• Determine the slope and Y-intercept

• Find the X-intercept
