Describe in your own words...
Slope
rise/run
(y2-y1/x2-x1)
y=mx+b
Linear Equation
m= slope
b= y-int
(x,y)
y = 3x
y= 5 ( x-2)
3x = 5x-10
4x + 3y = 5
-4x +3y = 15
Which numbers eliminate one another?
4x and - 4x
Y-Intercept
b in the slopeintercept equation
y=mx+b
point intersecting y axis
y=(-1/2)x-5
What is m? b?
m=(-1/2)
b=-5
y= -3x
y=5(x-(1/5))
-3x = 5x - 1
5x + y = 15
10x -2y = 2
-10x and 10
or 2y and -2y
Point of Intersection
Point where a system of equations intersect/meet
y=5(x-3)
m=5
b= -15
y = (-1/8x)
y= 12 + x
(-1/8)x = 12 + x
(-1/2)x + 15y = 30
(1/2)x - 15y = 15
-1/2 and 1/2
15 and -15
ordered pair / coordinate pair
(x,y) the way the point of intersection is written
y= (-3/2x) + 20
m=(-3/2)
b= 20
y= (x+2)^2

Give an example of a system of equations that can use the method of elimination.
You have 2 minutes
system of equations
two or more equations with all the same variables.
5x+4y=25
4y = 25 - 5x
y = (25/4) - (5/4x)
y = (9/3)x + 15
y = (-9/3)x - 15
