Answer:
<h2>y = 3x + 3</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The formula of a slope:
==============================================
From the table we have :
x = 1 → y = 6
x = 2 → y = 9
x = 3 → y = 12
x = 4 → y = 15
Calculate the slope (choice any two pairs, and calculate the slope):
(1, 6), (2, 9)
We have the equation:
Put the coordinates of the point (1, 6) to the equation, and solve it for b:
<em>subtract 3 from both sides</em>
Finally:

Answer is (4,-3) I’m pretty sure it’s right sorry if it’s wrong
Answer:
y = 60x + 20
Step-by-step explanation:
The number of hours that we ski is a variable cost where each hour costs $60. On top of that, we have a fixed cost of $20 which stays the same no matter how long we ski.
So we can use an equation to find the totla cost C given the number of hours t as follows:
C(t) = 60t + 20
We can use this equation to find the cost of a skiing session by plugging in some value for t. For example, if we ski for 3 hours:
C(3) = 60(3) + 20 = $200
The equation can also be written using x and y and mean the same thing.
