I need help with these :3 thx
1 answer:
Y = mx + b
where m is the slope and b is the y-intercept.
1. 2x + 3y = 12
3y = -2x + 12
y = -2x + 4
y-intercept is 4
2. x - 4y = 20
-4y = -x + 20
y = -x - 5
y-intercept is 5
3. y = 2x - 9
this one is easy because it's already in standard form
y-intercept is -9

Answer:
peter will have 123 stamps.
Step-by-step explanation:
This is because 53 times 3 is 159. Sarah has 159 stamps. Subtract 45 from 159 and you will get 123.
Answer: x=10
This is the answer I got.
Slope is y=mx+b
m=slope
b=y intercept
solve for y basically
3x-8y=5
minus 3x both sides
-8y=-3x+5
divide both sides by -8
3x15=45 and 17x15=255 so 45+255=300
