Consider this scatter plot. (A) How would you characterize the relationship between the hours spent on homework and the test scores? Explain. (B) Sally uses the function y = 5x + 45 to model the situation. What score does the model predict for 3 h of homework? (C) What does The number 45 in Part (b) mean in the context of the situation?

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5

c ) y = 2.5 x - 26.25
