How would we rewrite the equation of y = 1/3x -10 if we moved its graph down six units?

levacccp [35]

If you didn't change the slope of the line, but you moved it
down 6 units on the graph, then its y-intercept would become
6 less. The equation of the new line would be ...

y = 1/3 x - 16 .

Write a quadratic equation in factored form to model the given problem. Be sure to write the entire equation.

Veronika [31]

Equation :
[x(x+4)]/2=6 (as (b*h)/2=A)
x*x + 4*x -12 = 0

$x = -b+- \sqrt{ b^{2}-4ac }/2a$

so, x = 2 units(as -6 is negative)

Answer:

$(x-2)^{2} +(y+6)^{2} =49$

Step-by-step explanation:

equation of circle =

$(x-h) ^{2} + ( y-k)^{2} = r^{2}$

( h , k ) = center of origin

$r^{2}$ = radius

origin = ( 2 , -6 )

radius = 7

$(x-2)^2+(y+6)^2=49$
