Which function is graphed on the coordinate plane below? 0
х
f(x)
f(x) = 2x - 6
f(x) = 2x + 6
f(x) = -2x + 6
f(x) = -22-6

Option (4)

Step-by-step explanation:

Let the equation of the linear function is,

f(x) = mx + b

where m = slope of the line

b = y - intercept

Since slope of a line passing through two points and is defined by,

m =

Slope the line passing through (0, 6) and (3, 0),

m =

m = -2

y-intercept given in the graph 'b' = -6

Therefore, linear function will be,

f(x) = -2x - 6

Option (4) will be the answer.

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
