Answer:

Explanation:

B) Small triangle:

height = 20 - 15 = 5

base = 1

height to base = 5 :1

Medium triangle :

height = 60 -30 = 30

base = 2

height to base = 30 :2 = 15 :1

Large triangle:

height = 120 - 60 = 60

base = 4

height to base = 60 : 4 = 15 : 1

c) The ratios are same. This is true because wage and working hours are in direct proportion.

E) Take any two points. (1 , 15) & (2 , 30). Find the slope.

Slope = Change in y ÷ change in x

m = (30-15) ÷ (2 -1) = 15/1 = 15

y -y1 = m(x -x1)

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x - 15 + 15

y = 15x
