Linear or Proportional?
is y=mx proportional or linear
its Both
TRUE or FALSE: Proportional relationships MUST start at (0,0)
true
TRUE or FALSE: linear relationships can NOT start anywhere on a graph
False
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
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?
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 are proportional relationships all about
rate of change
in the equation y=mx+b what is b and what is mx
b is your y intercept and mx 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
TRUE or FALSE: x can be negative
FALSE
is y=-5x+b linear?
yes
If my line contains points (2,3) and (4,6) what is the slope?
3/2
7 toy whales cost 21$ what is the slope
3
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
is y=5x^2+b linear?
No
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
