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!
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:
Answer:
Cost is 7c+34.
Step-by-step explanation:
2(c+17) + 5c
=2c+34+5c
=7c+34
A = -65
b = 8
a * b = -65 * 8 = - 520
when multiplying, if the signs are different, then the product is negative
21, 15, 30
a+b+c=66
c=2b; a=b+6
(b+6)+b+(2b)=66
-6 -6
(b)+b+(2b)=60
2b+2b=60
4b =60
(1/4) 4b = (1/4)60
b= 15, which is the second number
