Graphing Points and Linear Equations

This lesson covers graphing linear equations using the equation y = x + 1. It demonstrates how to substitute values into the equation, calculate corresponding y-values, and plot these points on a coordinate grid. The lesson concludes with drawing a line through the plotted points, illustrating the graph of the equation.

What is the basic form of the linear equation introduced in this lesson?

• y = x + 1

• y = 2x + 3

• y = x - 1

• y = 3x + 2

If x is 2 in the equation y = x + 1, what is the value of y?

• 1

• 2

• 3

• 4

What is the y value when x is -4 in the equation y = x + 1?

• -5

• 0

• -3

• -2

When x is 0, what is the resulting y value in the equation y = x + 1?

• 3

• 2

• 1

• 0

How do you plot the point (2, 3) on a coordinate grid?

• Move right 3, up 2

• Move left 3, down 2

• Move left 2, down 3

• Move right 2, up 3

What is the correct movement to plot the point (-4, -3) on a coordinate grid?

• Move left 3, up 4

• Move right 4, up 3

• Move left 4, down 3

• Move right 3, down 4

What does a y value of 1 indicate when x is 0 on a coordinate grid?

• Move up 1

• Move down 1

• Move right 1

• Move left 1

What is the final step in graphing a linear equation after plotting the points?

• Erase the points

• Draw a line through the points

• Color the points

• Label the points
