(2,2.8)(4,5.6)
slope = (5.6 - 2.8) / (4 - 2) = 2.8/2 = 1.4
y = mx + b
slope(m) = 1.4
use either point (2,2.8)...x = 2 and y = 2.8
now we sub and find b, the y int
2.8 = 1.4(2) + b
2.8 = 2.8 + b
2.8 - 2.8 = b
0 = b
so ur equation is : y = 1.4x + 0..or just y = 1.4x
Answer:
(x, y) ⇒ (-x, -y)
Step-by-step explanation:
There are a couple of ways you can go at this.
1) Rotation by 180° in either direction is the same as reflection across the origin. That reflection is identical to reflection across both the x- and y-axes, in either order, so negates both coordinates. The transformation rule is ...
(x, y) ⇒ (-x, -y)
__
2) The rule for a general rotation by angle α is ...
(x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))
For α = 180°, sin(α) = 0 and cos(α) = -1. This makes the rule for rotation by 180° be ...
(x, y) ⇒ (-x, -y)
392+340f=f product is multiplying and plus is add
