use the equation y=mx+b
Written Question
m=slope
b=y-intercept
so, y=-3x+1
slope=-3x
y-intercept=1
the first picture--
you know the y-intercept is 2 right? sp y=x+2
slope is rise over run. Take two points
(2,0) and (3,1)
to get from (2,0) to (3,1) you go down one (-1) and right 3 (+3)
rise over run would be -1/3!!!!!!!!
y=-1/3x+2
the second pic--------
positive is when the line is pointing right
negative is when the line is pointing left
no slope is when it is a straight up or down line
undefined is when its not straight (curvy)
POSITIVE <3
Hope this helped, ask me for any more questions <3
