Answer:

Step-by-step explanation:
A=(1,21)
B=(3,15)
slope:- Δy/Δx=21-15/1-3=6/-2= -3
Equation:-
y-y1=m(x-x1)
y-21=-3(x-1)
⇒y=-21=-3n+3
→ y= -3n+3
<u>y= -3n+24</u>

Answer:
y = 42x
Step-by-step explanation:
since it is linear it is proportional
using y = mx + c where m is the gradient
working out the gradient pick any two coordinates, I'll use (6, 252) and (12, 504)


m = 42
input m = 42 in y = mx + c
the equation is now y = 42x + c
use one of the coordinates (6, 252) or (12, 504), I'm using (6, 252)
y = 42x + c where y = 252 and x = 6, solving for c:
252 = (42 × 6) + c
252 = 252 + c
c = 0
so the final equation is y = 42x
Answer:
-x^2 +8x -6
Step-by-step explanation:
Distribute the minus sign and collect terms.
(3x -8) -(x^2 -5x -2)
= 3x -8 -x^2 +5x +2
= -x^2 +8x -6
Answer:
for the first box the answer is 4x but I dont know the y intercept
Step-by-step explanation:
get 2 points the do y2-y1/x2-x1 then you get your x
