Answer:

y=2x-2

Step-by-step explanation:

the slope is y/x

the slope is 2 or 2/1

subtract 2 from the y value and 1 from the x value

(3-1,4-2) = (2,2)

keep doing this until you get a 0 in the x value

(2-1,2-2) = (1,0)

1 is your x-intercept

(1-1,0-2) = (0,-2)

-2 is your y intercept.

So now you know your y-intercept and your slope so you can now write your equation.

y=mx+b

m=slope, b=y-intercept

m=2, b=-2

substitute into the equation

y=2x-2

What is the distance between points A and B on the coordinate plane?

RoseWind [281]

Answer:

Step-by-step explanation:

use pythagorean theorem a^2 + b^2 = c^2

a = 6, b = 8

6^2 + 8^2 = c^2

100 = c^2

c = -10

since it cant really be negative, the distance becomes 10.

Find the sum of 3b/b+2 and 12/b+2 and express it in simplest form

CaHeK987 [17]

$\frac{3b}{b+2}+\frac{12}{b+2}=\frac{3b+12}{b+2}\\\\\\\frac{3b+12}{b+2}=\frac{3b+6+6}{b+2}=\frac{3b+6}{b+2}+\frac{6}{b+2}=\frac{3(b+2)}{b+2}+\frac{6}{b+2}=3+\frac{6}{b+2}$
