Answer:

y = 2x - 3

Step-by-step explanation:

Slope-intercept form is y = mx + b

m = slope

b = y-intercept

If you look at the graph, the y-intercept is on (0, -3) which means the y-intercept is -3.

If you look at the slope, you can use the rise/run method. Let's use 2 as an example. We would turn it into a fraction, 2/1. You then want to use the rise/run method. Starting from the y-intercept, go up the amount of the first number, and then go right the amount of the second number. So we would go up 2 and 1 right.

So this is our answer, y = 2x - 3

Find the tenth term of the geometric sequence, given the first term and common ratio.
Natalija [7]

Answer:

a_{10}=\dfrac{1}{128}

Step-by-step explanation:

In the geometric series:

a_1=4\\ \\r=\dfrac{1}{2}

The nth term of the geometric sequence can be calculated using formula

a_n=a_1\cdot r^{n-1}

In your case, n = 10, then

a_{10}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^{10-1}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^9\\ \\=2^2\cdot \dfrac{1}{2^9}\\ \\=\dfrac{1}{2^{9-2}}\\ \\=\dfrac{1}{2^7}\\ \\=\dfrac{1}{128}
