Answer:
a) y=11x+24
b) The slope of this equation is 11. You get the slope by taking the difference of the number of participants over the difference of the years: 35-57/1-3
c) The y intercept is 24 and it would be before the first year. (?)
d) There should be 79 participants in the fifth year.
Step-by-step explanation:
I hope this helped. I'm not 100 percent sure the explanation for letter c.
Put 3x + 3y = 45 in slope intercept form
y = 15 - 3/3x
(-3/3x is just going to simplify to -1x though)
Perpendicular form of -1x would be 1x
So your perpendicular slope would be 1
Answer:
Step-by-step explanation:
y = -
x + 3 ( equation of line t )
y - (- 2) = -
[ x - (- 2)] ⇒ y = -
x -
( equation of line u )
Answer:
y=250x+300
Step-by-step explanation:
Let x be the number of heaters and y be the total cost.
We need to find the linear function for y in terms of x.
It is given that company can produce 15 heaters for $4050 and 25 heaters costs $ 6550.
It means the line passes through the points (15,4050) and (25,6550).
If a line passes through two points
and
, then the equation of line is

The equation of line is




Add 4050 on both sides.


Therefore, the required linear function is y=250x+300.
