Answer:
y = x +
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (4, 6)
m = = , thus
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 6 ), then
6 = + c ⇒ c = 6 - = =
y = x + ← equation of line
A (-12,-8), B(6,-3), C(3,3)
Answer:
.
Step-by-step explanation:
Dilate a point by a scale factor of with as the center, and the resultant point would be at .
In this question:
Point to dilate: .
Scale factor: .
Center of dilation: .
The resultant point would be:
, which simplifies to .
It would be 8.5 because all you have to do is add 3 to 2.5 then you’ll get 5.5 then do that one more time.
