Answer:

b = -3, or (0, -3)

Step-by-step explanation:

As we move from (3,1) to (6,5), x increases by 3 and y increases by 4. Thus, the slope of this line is m = rise / run = 4/3.

Starting wth y = mx + b, we substitute 4/3 for m, 3 for x and 1 for y. Doing this results in:

1 = (4/3)(3) + b, which results in b = -3. Then the equation of this line is

y = (4/3)x - 3. The y-intercept is b, and b = -3.

Answer:

(1-5)/(3-6)= -4/-3= 4/3

y - 5= 4/3(x - 6)

y - 5 = (4/3)x - 8

y = (4/3)x- 3

y-int (0,-3): -3

The sum of the measures of the angles is 180. The sum of the measures of the second and third angles is two times the measure of

grigory [225]

Step-by-step explanation:

Let the first angle be $a$ degrees

Let the second angle be $b$ degrees

Let the third angle be $c$ degrees

It is given that sum of angles is $180$ degrees.

so, $a+b+c=180$ ...(i)

It is given that sum of the measures of the second and third angles is two times the measure of the first angle.

$b+c=2\times a$ ...(ii)

It is given that the third angle is 26 more than the second.

$c=26+b$ ...(iii)

using (ii) and (iii),

$b+b+26=2a$

$b+13=a$

using (i),(ii) and (iii),

$a+b+c=a+a-13+26+b=a+a-13+26+a-13=3a$

$3a=180$

$a=60$

$b=a-13=60-13=47$

$c=26+b=26+47=73$
