what happens if you're line has a straight slope
It means zero
The answer or solution to a liner system would is where two lines ___
Intersect
(x+3)(x+3) is not a perfect square
true or false
False it is a perfect square
What do the two lines mean on a triangle
The lines mean the same
The slope represents the ____ of change
rate
True or false
the y-int of y=8x-3 is -3
true
if two lines have the same slope and y-int they are called __
identical
What do we call a quadratic expressions when there is no middle bx term
Diffrence of squares
a2 +b2=?
C2
what is the slope and y-int of this
y=x-13
slope=1
y-int=-13
what graph has the steepest slope
a)y=4x+6
b)y=8x+7
c)y=2x-9
B has the steepest because its 8 and 8 is the highest
two
Factoring means rewriting the expression as a product of two binomials: ax2 + bx +c =(dx+e)(fx+g)
The sum of a triangle will always equal to what
180.
find the slope and y-int
y=-6/4x+7/2
slope=6/4
y-int=7/2
the slope of y=5x+3 is?
it is 5
-12= 2 + 5x + 2x
solve for x
-2 =x
a2 - b2 =(a+b)(a-b) is a perfect square
true or false
False it is difference of square
Jack is building a rocket ship for an at home project.The height of the rocket ship is 9 cm long and the length of its diagonal is 15 cm. What is the length of the base of the rocketship if it was twice as the of the base of the rocket ship
The base of the boat is 24 cm
A liner equation always graphs as a curved line
true or false
false they are always straight
solve for the variable
2w+5=3w-10
W=15
solve the equation by eliminating the fractions first
x-3/6 = x-2/4 -36
x=432
