Answer: The equation for the line in  point-slope form :(y+2)=\dfrac{-6}{5}(x-4)

The equation in slope-intercept form : y=\dfrac{-6}{5}x+\dfrac{14}{5}

Step-by-step explanation:

The equation of a line in point slope form passing through points (a,b) and (c,d) is given by :-

(y-b)=\dfrac{d-b}{c-a}(x-a)

Now, the point slope form passing through points (4, -2) and (9, -8) is given by :-

(y-(-2))=\dfrac{-8-(-2)}{9-4}(x-4)\\\\\Rightarrow (y+2)=\dfrac{-6}{5}(x-4)

The equation for the line in  point-slope form :(y+2)=\dfrac{-6}{5}(x-4)

Further if we simplify the equation , we get

y+2=\dfrac{-6}{5}x+\dfrac{24}{5}\\\\\Rightarrow\ y=\dfrac{-6}{5}x+\dfrac{24}{5}-2\\\\\Rightarrow\ y=\dfrac{-6}{5}x+\dfrac{14}{5}

The equation in slope-intercept form : y=\dfrac{-6}{5}x+\dfrac{14}{5}

Simplify this expression 9xy4x 3x3y​
Alekssandra [29.7K]

Answer:

81 x y^5

Step-by-step explanation:

Simplify the following:

9×3×3 x y^4 y

3×3 = 9:

9×9 x y^4 y

9 x y^4×9 y = 9×9 x y^(4 + 1):

9×9 x y^(4 + 1)

4 + 1 = 5:

9×9 x y^5

9×9 = 81:

Answer: 81 x y^5
