Find m and b
What is the slope and y-intercept for y=-3x+4
m= -3
b=4
y = 3x+2
Does this equation represent proportional relationship?
y = 1/2 x
yesssssssssss
If my slope is 0, what does that say about my line?
What is the slope and y-intercept for y=1/4x - 3
m = 1/4
b = -3
If m = 2 and b = 0 what is my equation?
y = 2x
Does this equation represent a proportional relationship?
y= 2x-5
Noooooooooooooo
What is the slope and the y-intercept of the line that passes through:
(0, 6) (2, 8)
y-int is 6 , slope is 1
For the line y = -x+5, is the slope positive or negative?
negative
If m = -4 and b = 7 what is my equation?
y = -4x+7
Do these ordered pairs represent proportional relationship?
(1, 3) (2, 6) (3, 9)
yes

(3, 3) (5,6) (7, 13)
Nooooooooooooo
When x is 0, what is the y value called?
y-intercept
What is the slope and y-intercept for y = x-8
m = 1
b = -8
If m = 1 and b = 0 what is my equation?
y = x
proportional
