Answer:
step 1. y - y1 = m(x - x1). this is the equation given a point and a slope.
step 2. find the slope m. m = (y2 - y1)/(x2 - x1) = (4 - (-4))/(0 - 2) = 8/-2 = -4.
step 3. y - (-4) = -4(x - 2) ; y + 4 = -4x + 8.
step 4. y = -4x + 4.
9:7
Ratios are always simplified so by dividing both 18 and 14 by 2 you get 9 and seven. Because yellow triangles is stated first the 9 is put before the 7 blue triangles.
Hello Croary
We would first need to subtract 13.09cm from 21.59cm which will be 8.5cm, with the left over space, divide in half
<u><em>8.5/2 = 4.25cm</em></u>
:)
The answer would be A because each x only has one y. Hope that makes sense!
