janna is saving money. her savings plan is shown below. janna has$34 and will save $6 per day. write an equation to repersent th

Romashka-Z-Leto [24]

For this case, the first thing we must do is define variables.
We have then:
x: number of days
y: amount of money saved
We then have the following equation that models the problem:
y = 6x + 34
Where,
34: is the initial amount of money that Janna has
6: amount of money she saves per day
Answer:
An equation to represent the relationship between the number of days and amount saved is:
y = 6x + 34

Use the two points to solve for m and b (5, 4), (-4, 3). Then write the final answer in slope-intercept form. Slope-intercept is

podryga [215]

Answer:

b=-31/9

Step-by-step explanation:

m=y2-y1/x2-x1

m=3-4/-4-5

m=-1/-9

m=1/9

y=mx+b

-4=1/9+b

-4+1/9=b

-31/9=b

How is a system of equations created when each linear function is given as a set of two ordered pairs. Explain

NNADVOKAT [17]

Answer:

Please check the explanation.

Step-by-step explanation:

If each linear function is given as a set of two ordered pairs, all we need is to find a slope between two lines and put one of the points in the slope- intercept form of the line equation to find the y-intercept 'b' and then writing the equation in the slope-intercept form. This is how we can generate a system of equations.

For example, let suppose a linear function has the following ordered pairs:
