Answer: 2, 1.5 , -0.75
(b) 
Step-by-step explanation:
Given
line is 
Converting it into intercept form

So, the x-intercept is
and y-intercept is 
The slope is given by

(b) the line perpendicular to the above line and passing through 
The slope of the required line

Equation of the line is given by

Answer:
z
Step-by-step explanation:
the y' should be 5 then 10 .20.40.80 since it double every day
Answer:
(From left to right) 2 5 8
Step-by-step explanation:
1. Find the gap (between the first and last terms) 11 - (-1) = 12
2. Divide by the number of times the linear term is added: 12/4=3
3. Use the common difference to find the missing values.
The slope of the line is 2 if that is what you're looking for
Well since you dont have the graphs posted i can tell u the y-intercept and the slope and you can figure it out from there.
8x-y=-4
-y=-8x-4
y=8x+4
the y intercept is 4 and the slope is positive 8
