For this case we have that by definition, the equation in the form of slope-intersection is given by:


y = mx + b

Where

  • m is the slope
  • b is the cut point

Substituting the given point: (x, y) = (2, -4) and the cutoff point b = -2 we can find the slope,


We have:


-4 = m * 2-2\\-4 = 2m-2\\-4 + 2 = 2m\\-2 = 2m

m =-\frac{2}{2}\\m = -1

Thus, the equation is given by:


y = -x-2

Answer:


y = -x-2

Change 2.6 from decimal to fractions show explanation
noname [10]

Answer:

Step-by-step explanation:

The 2 in 2.6 is in the ones place so we know that it equals 200. The 6 in 2.6 is in the tenths place so we know that it equals 60.  Add 200 with 60 to get 260/10. The denominator is 10 because 2.6 only extends to the tenths place.

Zepler [3.9K]
The first two terms are given, t_1=3 and t_2=4.

The third term, according to the formula, is

t_3=2\times4+3=11

and the next two terms are

t_4=2\times11+4=26
t_5=2\times26+11=63
