Answer:
The slope is 2
The slope represents how much it costs per visit the pool.
We have a positive slope when lines go from bottom left to top right
The y intercept is where we cross the y axis which is 4.
x is the number of visits to the pool
y is the total cost in dollars
f(x) = 2x+4
Explanation:
To find the slope we take two point ( 0,4) and (1,6)
and use the formula
m = (y2-y1)/(x2-x1)
= (6-4)/(1-0)
m= 2/1
The slope is 2
It represents how much it costs per visit the pool.
We have a positive slope when lines go from bottom left to top right
The y intercept is where we cross the y axis which is 4.
x is the number of visits to the pool
y is the total cost in dollars
f(x) = mx+b where m is the slope and b is the y intercept
f(x) = 2x+4
