Me with these questions about slope
6. identify the slope and y-intercept of the graph of the equation y = -3x + 1.
slope = -3, y-intercept = 1
slope = 1, y-intercept = 3
slope = 3, y-intercept = 1
slope = -3, y- intercept = -1

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
