20x + 4y
i’m not sure if this is 100 percent but i combined 8 + 12 since they were both x and then combined 5 + (-1) since they were both y then put in simplest form
Answer:
The answer to your question is f(x) = x + 4
Step-by-step explanation:
Data
A (-3, 1)
B (-2, 2)
C (-1, 3)
D (0, 4)
Process
1.- Find the slope
m = (y2 - y1) / (x2 - x1)
- Substitution
m = (2 - 1) / (-2 + 3)
Simplification
m = 1/1
Result
m = 1
2.- Find the equation of the line
y - y1 = m(x - x1)
Use point A (-3 , 1)
y - 1 = 1(x + 3)
Simplification
y - 1 = x + 3
Result
y =x + 3 + 1
y = x + 4
y = f(x) = x + 4
Multiply first equaton by -1 and add to first
-2x+y=7
<u>4x-y=-4 +</u>
2x+0y=3
2x=3
divide 2
x=3/2
sub
2x-y=-7
2(3/2)-y=-7
3-y=-7
minus 3
-y=-10
negative 1 times both sides
y=10
