8.4C Slope and Y-Intercept

The data in the table represents a linear relationship. Determine the slope and y-intercept of the line on which the points lie.

• m = 2; y-intercept = –1

• m = 1/2; y-intercept = –1

• m =1/2 ; y-intercept = 2

• m = 2; y-intercept = 1/2

Determine the slope and y-intercept of the line

• m = 1; y-intercept = 1

• m = 1; y-intercept = – 1 and 1/2

• m = 3/4 ; y intercept = 1

• m = 3/4 ; y-intercept = – 1 and 1/2

• –3; The amount of water in the fountain decreases 3 cm each day.

• –1; The amount of water in the fountain decreases 1 cm each day.

• 1; The amount of water in the fountain increases 1 cm each day.

• 3; The amount of water in the fountain increases 3 cm each day.

The graph shows the amount of money Leslie saved over a 6-week period. What do the slope and y-intercept mean?

• The slope of 15 means that the initial amount Leslie had was $15. The y-intercept of 30 means that Leslie saved $30 each week.

• The slope of 30 means that the initial amount Leslie had was $30. The y-intercept of 15 means that Leslie saved $15 each week.

• The slope of 15 means that Leslie saved $15 each week. The y-intercept of 30 means that the initial amount Leslie had was $30

• The slope of 30 means that Leslie saved $30 each week. The y-intercept of 15 means that the initial amount Leslie had was $15.
