Graphing Lines with Slope and Y-Intercept

The video tutorial by Squared explains how to graph lines using given slopes and y-intercepts. It starts with identifying the y-intercept on the y-axis and then uses the slope to determine the direction and distance to plot additional points. The tutorial covers graphing lines with negative, positive, zero, and fractional slopes, emphasizing the importance of connecting the points to form a straight line. The video provides a step-by-step approach to ensure understanding of graphing lines from slope and y-intercept data.

What is the first step in graphing a line when given the slope and y-intercept?

• Plot the slope

• Plot the y-intercept

• Draw the x-axis

• Draw the y-axis

If the y-intercept is -1, where do you plot the first point on the y-axis?

• At -2

• At 0

• At -1

• At 1

For a slope of -1/4, if you choose the bottom number to be negative, what direction do you move?

• Down 1, Left 4

• Up 1, Right 4

• Down 1, Right 4

• Up 1, Left 4

What is the y-intercept of the second line?

• 1

• 2

• 3

• 4

For a slope of 3, how do you move from the y-intercept point?

• Down 1, Left 3

• Up 1, Right 3

• Up 3, Right 1

• Down 3, Left 1

What is the y-intercept of the third line?

• -6

• -3

• -4

• -5

What type of line is formed when the slope is 0?

• Curved

• Vertical

• Diagonal

• Horizontal

What is the y-intercept of the fourth line?

• 2

• 3

• 5

• 4

For a slope of 2/3, if you choose to go up 2, what direction do you move next?

• Left 3

• Right 2

• Left 2

• Right 3

What is the final step after plotting all the points for a line?

• Erase the points

• Draw the x-axis

• Connect the dots

• Label the points
