Graphing a linear equation using a table x + y = 4

The video tutorial covers graphing equations using intercepts and tables. It begins with an introduction to graphing, explaining how to use X and Y intercepts to plot points on a graph. The instructor then demonstrates how to use a table of values to graph equations, emphasizing the importance of choosing appropriate values. The tutorial concludes with a discussion on selecting values for graphing and understanding vertical lines.

What is the X-intercept of the equation when Y = 0?

• X = 4

• X = 0

• X = -4

• X = 2

How do you write the point for X = 4 and Y = 0?

• (0, 4)

• (0, 0)

• (4, 4)

• (4, 0)

What is the first step in plotting points on a graph?

• Draw the axes

• Choose random points

• Find the intercepts

• Connect the points

How many points are needed to create a line using a table?

• Three

• Four

• Two

• One

What is the Y value when X = -3 in the equation X + Y = 4?

• Y = 7

• Y = 4

• Y = -3

• Y = 1

Which range of values is recommended for choosing points when using a table?

• Between -5 and 5

• Between -2 and 2

• Between -10 and 0

• Between 0 and 10

What type of line is formed when X is always equal to a constant value?

• Curved line

• Diagonal line

• Horizontal line

• Vertical line
