Answer:
Step-by-step explanation:
first, we need to find the slope
slope = (y2 - y1) / (x2 - x1)
(-2,1)...x1 = -2 and y1 = 1
(0,8)...x2 = 0 and y2 = 8
now sub
slope = (8 - 1) / (0- (-2) = 7/(0 + 2) = 7/2
point slope form : y - y1 = m(x - x1)
using point (-2,1)....x1 = -2 and y1 = 1
slope(m) = 7/2
now sub
y - 1 = 7/2(x - (-2) =
y - 1 = 7/2(x + 2) <==== here is one answer
y - y1 = m(x - x1)
using point (0,8)...x1 = 0 and y1 = 8
slope(m) = 7/2
now sub
y - 8 = 7/2(x - 0) <===== another possible answer

Step-by-step explanation:
Answer:
1) $283.50
2) 65.21 meters.
Step-by-step explanation:
Part 1)
We know that a spool of ribbon holds 6.75 meters.
A craft club buys 21 spools.
So, the total length of ribbon bought is:
Each meter costs $2. So, the total cost will be:
Part 2)
A spool holds 6.75 meters.
We bought 21 of them, so that total length we have is 141.75 meters.
The club used 76.54 meters.
So, the amount of ribbon that is left is represented by:
Subtract:
So, 65.21 meters of ribbon will be left.

Step-by-step explanation:
A negative exponent in the numerator is equivalent to a positive exponent in the denominator, and vice versa.
... a⁻² = 1/a²
