Finding the x and y intercepts of a linear graph y= 4 + 2x

The video tutorial explains how to find the X and Y intercepts of a graph. It begins with an introduction to intercepts, followed by a detailed explanation of X intercepts, including how to identify and calculate them. The tutorial then covers solving for X intercepts using equations. Finally, it explains Y intercepts, detailing how to identify and calculate them from the graph.

What is the X intercept of a graph?

• The point where the graph crosses both axes

• The point where the graph crosses the X-axis

• The point where the graph crosses the Y-axis

• The point where the graph does not cross any axis

Which of the following is true about coordinate points?

• They do not have any values

• They only have a Y value

• They only have an X value

• They consist of both X and Y values

How do you isolate the variable X in the equation 0 = 4 + 2X?

• Add 4 to both sides

• Multiply both sides by 2

• Subtract 4 from both sides and then divide by 2

• Divide both sides by 4

What is the X intercept of the equation 0 = 4 + 2X?

• X = -4

• X = 2

• X = 4

• X = -2

How do you find the Y intercept of the equation Y = 4 + 2X?

• Set X to 0 and solve for Y

• Set X to 4 and solve for Y

• Set Y to 0 and solve for X

• Set both X and Y to 0
