Algebra sol review

yeahhh

ms. piazza gave us these

i just typed them up

kAt

Terms

undefined, object
copy deck
associative property of multiplication
(ab)c=a(bc)
reflexive property
a=a
multiplicative inverse
a(1/a)=1
multiplicative identity
a*1=a
transitive
if a=b and b=c, then a=c
point slope form
y-y₁=m(x-x₁)
domain
all the possible x values
symmetric property
if a=b, then b=a
how to find the zeros, roots, or solutions of a function
substitute 0 in for y or f(x)
a+0=a
substitution property
if a=b, then a can be replaced by b
constant of variation
k in a direct variation equation (slope)
(a+b)+c=a+(b+c)
commutative property of multiplication
ab=ba
a+(-a)=0
a+b=b+a
standard form
Ax+By=C, where A, B and C are integers. A is positive integer. A, B and C have no GCF other than 1. A and B can't both be zero
range
all the possible y values
direct variation
y=kx
zero product property
if ab=0 , then a=0 or b=0 or both a and b equal zero
slope
(y₂-y₁)/(x₂-x₁)
multiplacative property of zero
a*0=0
distributive property
a(b+c)=ab+ac
slope-intercept form
y=mx+b
