The equation is y2-y1/ x2-x1
so 6-4/ -6+4, 2/-2, reduced is -1 the slope is -1
Answer:
ight so PSAT means pre-SAT. it doesn't affect your grade. an it don't affect yo chances of getting into college. they wanna see where errybody at, you still wanna do yo best. its preparing you for the SAT i took the psat when i was in 8th grade an they want you to take that shi seriously. buh dont stress about it. they give you plenty of time. im in 10th. buh you finna do great you jus gotta trust in yoself
LY = 5.2 , TY = 3.9
Δ LTN is a right triangle , ∠T = 90° , TY⊥LN
∴ TY² = LY * YN
∴ 3.9² = 5.2 * YN
∴ YN = 3.9²/5.2 = 2.925
∴ LN = LY + YN = 5.2 + 2.925 = 8.125
Δ LYT is a right triangle , ∠Y = 90°
LT² = LY² + YT² = 5.2² + 3.9² = 42.25
∴ LT = √42.25 = 6.5
Δ NYT is a right triangle , ∠Y = 90°
NT² = NY² + YT² = 2.925² + 3.9² = 23.765
∴ NT = √23.765 = 4.875
The preimeter of the rectangle LINT = 2 * (LT + TN)
= 2 * ( 6.5 + 4.875 )
= 2 * 11.375
= 22.75
Answers:
x = 9
y = -3
==============================================================
How to get those answers:
Simply multiply the coordinates of the point (3,-1) by the scale factor 3.
The new x coordinate will be 3*3 = 9 and the new y coordinate will be -1*3 = -3.
The point (3, -1) moves to (9, -3) after applying the dilation.
The rule I used is 
where k is the scale factor, which is k = 3 in this case.
Note how k > 1 means the point moves further away from the origin. It also means we have an enlargement.
