Answer:
by showing dots and correlations in a graph which will have an estimated slope, while not a definite one
Step-by-step explanation:
Step-by-step explanation:
x= (70+83+90)/3= 81
85=(89+75+y)/3
255=89+75+y
y=91
92=(86+a+a)/3
276=86+2a
2a=190
a=95
93=(b+b+b)/3
279=3b
b=93
Answer:
y=1/2x + 3
Step-by-step explanation:
Slope is ∆y/∆x. In this case,
m = (6-3) / (6-0) = 3/6 = 1/2
Y-intercept is what the y-value is when the line intersects the y-axis. Because of the point (0,3), you know it's 3.
Answer:
the answer would be the first one
Step-by-step explanation:
Your domain is your x and your range is y.
Answer: (1) 13/20 (2) 8 (3) Yes. They are proportional
<u>Step-by-step explanation:</u>
(1) 13 students take the bus.
33 - 13 = 20 students do not take the bus
(2)
(3)
All of the fractions simplify to the same number so they ARE proportional.
