Answer:
y=1.4x+6.8
Step-by-step explanation:
(-2;4) (-7;-3)
4=-2k+b
-3=-7k+b
7=5k
k=1.4
-2.8+b=4
b=6.8
I already know k and b so I can write an equation.
y=1.4x+6.8

Step-by-step explanation:
For the day blanks, you just multiply the number of weeks by 7.
For the week blank, you divide 63 by 7
I can run that mybe 40 times
Answer:
Step-by-step explanation:
y=-3x+13
y = mx + b, where m is the slope and b is the y-intercept.
A line parallel to this line will have the same slope, -3. We can start by writing:
y = -3x + b
No matter what is chosen for the value of b, this line will be parallel. We do want the line to go through point (6,10), however. The way that can be done is to find a value of b that would shift the line to go through (6,10).
Find b by entering the point (6,10) into the equation, and then solve for b:
y = -3x + b
10 = -3(6) + b
10 = -18 + b
b = 28
The line becomes y = 3x + 28
See the attachment.
A quadratic function:

First, take the point (0,-4) and plug the values (x,y) into the equation:

So the equation is

.
Now plug the values of the other two points into the equation and set up a system of equation:

The function is:
