The y-intercept of this regression line is 11. What does this tell you about the relationship between the amount of fertilizer and the height of the seedlings?Group of answer choicesIf 11 grams of fertilizer are used, the average seedling will be about 0 cm tall.If no fertilizer is used, the average seedling will be about 9 cm tall.If 11 grams of fertilizer are used, the average seedling will be about 11 cm tall.If no fertilizer is used, the average seedling will be about 11 cm tall.

Sagot :

if no fertilizer is used, the average seedling will be about 11cm tall (option D)

Explanation:

The y-interept = 11

Y-intercept is the value of the height of seedlings when the mass of the fertilizer is zero.

Comparing the options with the graph:

a) From the graph, if 11 grams of fertilizer is used, the height will be around 20cm not 0cm.

This option is wrong.

b) if no fertilizer is used, the height of the seedling will be around 11cm not 9cm tall

c) If 11 grams of fertilizers is used, the seedling will be around 20cm not 11cm tall

d) If no fertilizer is used, the height of the seddling will be around the y-intercept on the line.

This because no fertilizer means the mass is zero and on the grapg the height is the y-intercept (11cm)

Hence if no fertilizer is used, the average seedling will be about 11cm tall (option D)
