For the following sequence determine the common difference (if it is an arithmetic

1 answer:

6 0

Arithmetic = uses addition
Geometric = uses multiplication

60 - 36 = 24
60 + 24 = 84 (does not give you 100)
Proving this is not Arithmetic

60/36 = 5/3 or 1.66666667
100/60 = 5/3 or 1.66666667

Solution: geometric
Common ratio = 5/3

Write the point -slope form of the equation of each line given the slope and y-intercept. Slope=(2/3), y-intercept =0

MakcuM [25]

Answer:

$\large\boxed{y-0=\dfrac{2}{3}(x-0)\to y=\dfrac{2}{3}x}$

Step-by-step explanation:

The point-slope form of ane equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point on a line

We have:

$m=\dfrac{2}{3}$

y-intercept is for x = 0.

Therefore, if y-intercept = 0, then we have the point (0, 0).

$y-intercept=0\to(0,\ 0)$

Substitute:

$y-0=\dfrac{2}{3}(x-0)\to y=\dfrac{2}{3}x$
