Slope
What is the Slope?
6-3/-6-1
-4
Change to Slope-Intercept
9x+6y=18
y=-3x+6
Turn this into Point-Slope Form
(1,2) m=3
(y-2)=3(x-1)
Turn this into Slope-Intercept Form
2x+1y=4
y=-2x+4
What is the Slope formula?
M= y1-y2/x1-x2
Is 4 the Slope of 2-1/1-2?
No
What is the y-intercept?
y=7x+2
2
Put this into Slope-Intercept Form.
(y-5)=6(x-2)
y=6x+-7
Is this in Standard Form?
-1/2x+4y=8
If it is not in Standard Form what is wrong with it?
It can't be negative, a fraction, and the G.C.F. has to be 1
What is Slope Intercept Formula?
y=mx+b
How do you get the slope of these points?
(5,3) (4,7)
You subtract y1 and y2 and then subtract x1 and x2.
Change to slope-intercept
8x+8y=4
y=-x+1/2
Define all of the parts of Point-Slope Form.
Y1=your Y
X1=your X
Change this into Slope-Intercept Form
1x+4y+9
y=1/4x+2.25
What is Point Slope form?
(y-y1)=m(x-x1)
What is the Slope of
(12,6) and (4,6)?
-3
describe the parts?
y=mx+b
x is the Slope
b is the Y-Intercept
Put this into Point-Slope
(5,-3) M=7
(y--3)=7(x+5)
or
(y+3)=7(x+5)
Solve for Y
6x+3y=3
y=-2x+3
What is the Standard form Equation?
Ax+By=C
What is the Slope of
(23,2) (69,6)?
M= (-46,-4)
Turn into slope-intercept.
8x+2y=6
y=-4x+3
Put this into Point-Slope
(16,26) M=38
(y-26)=38(x+16)
Solve for Y
534x+233y=785
Y=-2.3x+3.4
What is the meaning of B
The Y-Intercept
