Help!!!How does the slope of g(x) compare to the slope of f(x)?

attashe74 [19]

we know that

The formula to calculate the slope m between two points is equal to

$m=\frac{(y2-y1)}{(x2-x1)}$

Step $1$

Find the slope of the function f(x)

Let

$A( 0,-2)\\B(1,0)$

substitute the values in the formula above

$m=\frac{(0+2)}{(1-0)}$

$m=2$

the slope of the function f(x) is $m=2$

Step $2$

Find the slope of the function g(x)

Let

$C( -4,0)\\D(0,2)$

substitute the values in the formula above

$m=\frac{(2-0)}{(0+4)}$

$m=\frac{2}{4}$

$m=\frac{1}{2}$

the slope of the function g(x) is $m=\frac{1}{2}$

therefore

slope f(x) > slope g(x)

slope g(x) < slope f(x)

the answer is the option

B.The slope of g(x) is less than the slope of f(x).

Find the coordinates of a point that divides the directed line segment XY in the ratio 2:6. answers: A) (3, 5) B) (–1, –3) C) (0

Stells [14]

Answer:

Option D.

Step-by-step explanation:

Let the coordinates of a point which divides the segment XY in the ratio of m : n is (x, y).

Segment X(-4, -9) and Y(4, 7) has been divided in the ratio of 2 : 6.

Therefore, x = $\frac{[4m+n(-4)]}{m+n}=\frac{8-24}{2+6}$

= - $\frac{16}{8}$

= -2

and y = $\frac{[7m+n(-9)]}{m+n}=\frac{14-54}{2+6}$

= $-\frac{40}{8}$

= -5

Therefore, the point (x, y) is (-2, -5).

Option D. will be the answer.
