10= z/4 times by 4... z/4 x 4 (4 cross out just left with z) 10 x 4 = 40. z=40
is the equation equals out then it has a solution.
solutions for equations are all real numbers
if the equation does not = ex: -6 = 0. then the answer is no solution
< or ( ) is open/ does not include the number
<_ (arrow with line under it) or [ ] means it includes number
>3 number is smaller than 3
<3 3 is the bigger number
if you divide by a - in an inequality then you flip the > sign
-2x < 6 is x> -3
x+5>9 is x>4
x-3<4 is x < 7
for graphing you count quads left down right. like a C 1, 2, 3, 4
quad one is (+, +)
quad 2 is ( -, + )
quad 3 is (-, - )
quad 4 is (+, - )
pairs (3,7) and (0,1) y=2x+1 1st point is (3,7) second point is ( 0, 1). ex. 2 (3) + 1 =7
for y intercept y= mx+b
y intercept is (0,b)
x intercept is (a, 0)
y axis is up and down (vertical)
x axis is across (horizontal)
the __is the difference of the y-values of two points on a line rise
the ___ is the difference in the x-values of two points on a line run
the ___ of a line is the ratio of rise to run for any two points on the line. slope
slope= rise/run or change in y/ change and x
zero slope is flat horizontal y=b
undefined slope is straight vertical x=a
to find the slope when given 2 points the equation is y2-y2/ x2-x1
the m in y=mx+b is the slope
the b in the y=mx+b is the y intercept
to find the equation of the line the equation is y-y1=m(x-x1)
to make an equation from 2 points you do 1. y2-y1/x2-x1 and then y-y1=m(x-x1)
