Answer:
1) y = -2/3x - 4
2) y = -3x + 7
Step-by-step explanation:
1) Plug in the slope (m) and y intercept (b) into the equation
y = mx + b
y = -2/3x - 4
2) Find the slope (m) m = y₂ - y₁/ x₂ - x₁
m = 4 - (-2)/1 - 3
m = 6/-2
m = -3
Then find the y intercept (b) by plugging x, y and m into y = mx + b (you can choose either point given
4 = -3 ( 1) + b
4 = -3 + b
Add 3 to both sides
7 = b
So now you know m = -3 and b = 7
Plug into y = mx + b
y = -3x + 7
Slope Intercept: Y=mx + b
1. Y= -2/3x + -4
2. Y= 1/3x + 7

Answer:
Step-by-step explanation:
we have a 51 in sandwich
let a piece be x
we have x= shorter piece
another piece is x+6
another piece (x+6)-9=x-3
x+x+6+x-3=51
3x=51-3
3x=48
x=48/3=16
x=16, longer piece is 16+6=22, shorter piece =10
-9/ 3= -3
-3 + -4 + -2 = -9
the numbers are -2 , -3 , -4
