What is an equation of the line in slope-intercept form? m = two-sevenths and the y-intercept is (0, –12) a. y =two-seventhsx+ 12 b. y = two-seventhsx – 12 c. y = 12x–two-sevenths d. y = 12x + two-sevenths

y = (2/7)x -12  (Answer Choice B)

Step-by-step explanation:

Take the given values (  m=2/7 and y-intercept (0,-12)  ) and substitute them into y = mx + b:

y = (2/7)x -12

answer: i can’t tell you that

step-by-step explanation:

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
