A printing firm charged $35 for printing 600 sheets and $47 for printing 800 sheets find the formula assuming the relationship i
saveliy_v [14]
Here, Coordinates are: (35, 600) & (47, 800)
Now, Slope (m) = y2 - y1  /  x2 - x1
m = 800 - 600 / 47 - 35
m = 200 / 12 = 100 / 6
m = 50/3

Take any one coordinate into slope-intercept formula:
y - y1 = m(x - x1)
y - 600 = 50/3 (x - 35)
y - 600 = 50x/3 - 1750/3
y = 50x/3 + 50/3

In short, Your Answer would be: y = 50x/3 + 50/3

Hope this helps!

The cost of a gym membership is $25 per month. There is an initial fee of $40
IceJOKER [234]

Answer:

y = 25x + 40

Step-by-step explanation:

Using the formula, y = mx + b we can find out what this equation would be.

m = the rate of change/slope

b = the y- intercept

25 per month is telling us that this is the rate of change.

Since the $40 is only paid once, you can tell that this is the y intercept.

The equation will look like:

y = 25x + 40

On a graph it would look like:

If a = − 65 and b = 8, the product of a x b models which rule for multiplying integers? What is the product?
Alex Ar [27]
A = -65
b = 8

a * b = -65 * 8 = - 520

when multiplying, if the signs are different, then the product is negative
