Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and

nevsk [136]

Step-by-step explanation:

Points are (8,5) and (-12,-9)

The equation of a line passing through two points is given by :

$y-y_1=m(x-x_1)\ \text{m is slope}\\\\y-5=\dfrac{y_2-y_1}{x_2-x_1}(x-8)\\\\y-5=\dfrac{-9-5}{-12-8}\times (x-8)\\\\y-5=\dfrac{7}{10}\times (x-8)\\\\10y-50=7x-56$

$-50+56=7x-10y\\\\7x-10y=6$

But he writes the equation 7x – 10y = 3 which is not matching with the one we have calculated. It means that model calculated by Devon is not good.

H(2) =<br> Someone pls help

Anna71 [15]

Replace n with 2 in the bottom equation.

h(2) = h(2 - 1) + 2

h(2) = h(1) + 2

We are given that h(1) is -2. See it?

So, h(2) = -2 + 2, which is 0.

Answer: h(2) = 0.

Got it?
