Intercepts

100

What is Slope?

Intercept form of a line 

200

point slope form of a line

(y-y¹) = m (x-x¹)

300

A difference between parallel and perpendicular lines 

Parallel have the same slope and perpendicular have negative receival slopes.

400

x-2y=8

x int= x-2(0)=8

x=8 

y int= (0)-2y=8

y=8

500

2x-4y=8

x int= 2x-4(0) = 8

x=4

y int= 2 (0) -4y =8 

y=-8
