WILL MAEK BRAINLIST Given the points (-7, 4) and
(0, - 2) on a line, find the values of m and b.

m =
b=

Enter your answers as integers and/or as reduced fractions in the form A/B.

m = -6/7

b = -2

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1) = (-2 - 4)/(0 - (-7)) = -6/7

y = mx + b

m = -6/7

y = -6/7 x + b

Use point (-7, 4).

4 = (-6/7)(-7) + b

4 = 6 + b

b = -2

y = -6/7 x - 2

m = -6/7

b = -2

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
