(0,5)(3,-1)
slope = (-1 - 5) / (3 - 0) = -6/3 = -2
y = mx + b
slope(m) = -2
(use either of ur points...(0,5)...x = 0 and y = 5
now we sub and find b, the y int
5 = -2(0) + b
5 = b
so ur line is : y = -2x + 5
90+2 so 9 tens and 2 ones
10+10+10+10+10+10+10+10+10+10 = 9 tens or 90
1+1= 2 ones or 2
So the pencils all together would be $6 so divide that by 3 and you get D as your answer each pencil costs $2
Answer:
3/12 for red
4/12 for blue
Step-by-step explanation:
3 is red
5 is green
4 is blue
3 + 5 + 4 is 12 so it is out of 12 altogether
3/12 for red
4/12 for blue
3.6 minus 2.4 equals 1.2. then 1.2 divided by -0.8 equals -1.5
