EXPLANATION
To find the slope, you
divide the difference of
the y-coordinates of a
point on a line by the
difference of the xcoordinates

EXPLANATION
There are other special
symbols that show in what
way things are not equal. a
< b says that a is less than
b. a > b says that a is
greater than b. (those two
are known as strict
inequality) a ≤ b means
that a is less than
or equal to b.
EXPLANATION
Counting numbers are the set
of numbers that we use to learn
how to count. 1, 2, 3, 4, 5, and so
on. They are also called
natural numbers—maybe since
they feel natural to us because
they are naturally the first
numbers we learn. Sometimes
they are also referred to as
positive integers.
EXPLANATION
A line is said to
be perpendicular to
another line if the
two lines intersect at a
right angle.
EXPLANATION
y – 4 = -2(x+1)
y – 4 = -2x -2 (distributive property)

EXPLANATION
i. Given:
*slope=7
*point: (0,4) {y-intercept}
ii. Plug given into y = mx + b
*y = 7x + 4
EXPLANATION
Given:
i. Point A(3, -1), B(-3, 5)
Δ𝑦
ii. Find slope using Δ𝑥
iii. 5 – (-1) 6 -1
-3 – 3
-6
iv. Point slope form: y – y1 = m(x – x1)
y – (-1) = -1(x – 3)
y + 1 = -x +3

DAILY
DOUBLE!!!
EXPLANATION
EXPLANATION
EXPLANATION
Jose wants to ride his bike a
total of 50 miles this
weekend. If he rides m miles
on Saturday, what expression
represents the number of
miles he must ride on
Sunday?
 Total # of miles he wants to
ride is 50.
 He rides m miles on
Saturday
50 – m would be the
equation since 50 is the total
and m is a part.
EXPLANATION
The product of a number and 3,
increased by 5, is 7 less than twice
the number. What equation can be
used to find this number, n?
Product of a number and 3; 3x
Increased by 5; +5
Is; =
7 less than; - 7
Twice the number; 2x
3x + 5 = 2x - 7
3x + 5
2x - 7
EXPLANATION
The square of a positive number is
24 more than 5 times the number.
What is the value of the number?
 32= 9 ; 3 • 5 = 15 ; 9 is not 24 more
than 15.
 62 = 36; 6 • 5 = 30; 36 is not 24
more than 30.
 82 = 64; 8 • 5 = 40; 64 is 24 more
than 40.
 42 = 16; 4 • 5 = 20; 16 is not 24 more
than 20.
EXPLANATION
 Owino gets paid $280 per week plus
5% commission on all sales for selling
electronic equipment. If he sells n
dollars worth of electronic equipment
in one week, what algebraic
expression represents the amount of
money?
 $280 per week; he initially gets paid
$280 in the beginning of each week
 Plus 5% commission on all sales; .05 *
n since we don’t know the amount of
commission on sales.
