Alg1ACP - Point Slope Review

 $y=m\left(x-x_1\right)-y_1$  

 $y=m\left(x-y_1\right)+x_1$  

 $y=m\left(x-x_1\right)+y_1$  

 $y=m\left(x+y_1\right)-x_1$  

Flip the sign on $x_1$

Flip the sign on $y_1$

Y-intercept is when $x=0$

Slope is $\frac{run}{rise}$

$y=-\frac{2}{3}\left(x+6\right)+4$

$y=-\frac{2}{3}\left(x-6\right)+4$

$y=-\frac{2}{3}\left(x+4\right)+6$

$y=-\frac{2}{3}\left(x-4\right)+6$

Step 1: Graph the slope

Step 1: Graph the point (-4,1)

Step 1: Graph the point (4,1)

Step 1: Graph the point (1,-4)

Step 2: Go up 2 right 1 to find another point

Step 2: Go down 2 right 1 to find another point

Go up 1 right 2 to find another point

Step 3: Draw the line

Step 3: There is no step 3

Slope = -6/5

Slope = -5/6

Slope = 2/1

Slope = 1/2

$y=\frac{1}{2}\left(x+4\right)-6$

$y=\frac{1}{2}\left(x-4\right)-6$

$y=\frac{1}{2}\left(x+8\right)-4$

$y=\frac{1}{2}\left(x-8\right)-4$
