Linear or Proportional?
is y=mx proportional?
Yes
TRUE or FALSE: Proportional relationships MUST start at (0,0)
true
TRUE or FALSE:
Linear relationships can start anywhere on the y-axis.
True, a linear relationship can have a y-intercept
TRUE or FALSE: Slopes can be crooked
False
TRUE or FALSE: proportional equations are the same as linear equations
False
is y=mx+b proportional or linear?
Linear, to be proportional it wouldn't have a y-intercept!
what is the equation for proportional relationships
y=mx
what is the equation for linear equations
y=mx+b
what is the formula for slope from a graph?
rise/run
what is your constant rate of change if you have the points (3,2) and (6,4)
2
what is the difference between proportional and linear relationship
a linear relationship has a y-intercept
What is the only number in a proportional relationship?
The slope or rate of change
in the equation y=mx+b what is b and what is mx
b is your y intercept and m is your slope
how can I tell if a slope is negative or positive
(detailed explanation)
if the line is going upwards left to right it is positive.
if the is going downwards left to right it is negative.
Solve y=2x+6
y=8
X=-2
are proportional relationships linear?
Yes
What is the slope in the equation
y=1/3x
1/3
If my line contains points (2,3) and (4,6) what is the slope?
3/2
I run 3 miles in 2 hours. what is the slope
1.5
Are all linear relationships proportional?
No
what does the m in y=mx mean
it means constant of proportionality, rate of change and the slope
7 toy whales cost 21$ what is the slope
3$ per whale
TRUE or FALSE: when 6 robots cost 24$, 13 robots cost 50$
False
