What is the y-intercept of y = 2/3x + 2 a) (2, 3) b) (3, 2) c) (0, 2) d) (-3, 0)

C) (0, 2)

Step-by-step explanation:

y = 2/3x + 2

This is in the form y = mx+b

b is the y intercept  

We have the y intercept when x=0

(0,b)

(0,2)

C) (0, 2) is your answer

Step-by-step explanation:

Note the equation:

y = mx + b  is the equation used in y = (2/3)x + 2

m is the slope ; b is the y-intercept.

You are solving for the y -intercept, which is b. b = 2, therefore, 2 is your y.

Also note that when you are solving for the y-intercept, x must = 0 (& vice versa for when you are solving for x -intercept.)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
