Answer:
y = -1/3 x
Step-by-step explanation:
what is the slope intercept form for x+3y=0
Slope intercept form solves for y:
x + 3y = 0
subtract x from both sides:
x + 3y - x = 0 - x
3y = -x
divide both sides by 3:
3y/3 = -x/3
y = -1/3 x
Answer:
(x,y)=(-2,-5)
Step-by-step explanation:
y=1/2x-4
y=-2x-9
(y=) 1/2x-4=-2x-9
1/2x +2x=-9+4
1/2x +4/2x=-5
5/2x=-5
5x=-5*2
5x=-10
x=-2
x=-2
y=-2x-9=-2*(-2)-9=4-9=-5
(x,y)=(-2,-5)
-6 x -6 x -6 = -216
-6 + -6 + -6 = -18
So the answer is negative 6
Before dilation:
the height of the triangle is h₁ = 7 - (-1) = 8
the width of the triangle is w₁ = 7 - (-5) = 12
After dilation:
the height of the is h₂ = 9-7 = 2
the width of the triangle is w₂ = -5 - (-8) = 3
The scale factor is h₂/h₁ = 2/8 = 1/4 = 0.25
Also, the scale factor is w₂/w₁ = 3/12 = 1/4 = 0.25
Answer: The scale factor is 0.25
Answer:
A, B, C and D.
