Answer:
Step-by-step explanation:
The form of the equation you are given is called "point-slope" form. The "slope" in this case is the per-hour fee. The point is (9 h, $195). Point-slope form generally looks like this:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
Here, you have m=15, (h, k) = (9, 195), so the equation looks like ...
y -195 = 15(x -9)
__
The "one-time fee" is the cost when hours are zero.
y -195 = 15(0 -9)
y = 195 -9(15) = 60 . . . . add 195 to both sides, and evaluate
The one-time fee is $60.
The Y-Intercept is where the line intercepts on the Y axis of the graph. The slope of a graph is the rate the data is increasing or decreasing at.

Step-by-step explanation:
a. no. 9 x 15 = 135, so if she sells more than 15 necklaces, she'll make a profit
b. 50n > 135 + 4.50n
Answer:
a₁ = 7
r = 3
a_n = a_1(rⁿ⁻¹)
a₁₀ = 7(3¹⁰⁻¹
a₁₀ = 7(3⁹)
a₁₀ = 7(19683)
a₁₀ = 137 781
