What is the slope of the line.

3/4

Step-by-step explanation:

Start from the y-intercept (-1). Find another point that is on the line. I am using the point (0, -1) and also (4, 2).

Next, use the slope form, rise over run. In this case, you can also use the formula (y² - y¹) / (x² - x¹).

Plug in the values, and you get 3/4. So, the slope is 3/4.

Also, you can count from one point of the line up and to the right in this problem to find the slope.

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
