A line includes the points (8, 6) and (4, 5). What is its equation in slope-intercept form?
Pie

Answer:

y=1/4x+4

Step-by-step explanation:

to find the slope use (y2-y1)/(x2-x1)

(5-6)/(4-8)= 1/4

1/4 is your slope

to find the b in y=mx+b, plug in 1/4 for m and choose one of the points to plug in for x and y

I will use (4, 5)

5=1/4(4)+b

5=1+b

4=b

the final equation in y=1/4x+4

hope this helps!

Let Theo's siste can paint a fence in x times

Given.

Theo can paint a fence three times as fast as his sister can. Working together, they can paint a fence in 9 hours.

\frac{1}{x}+\frac{1}{3x} =\frac{1}{9}\\\frac{3+1}{3x} =\frac{1}{9} \\\frac{4}{3x}=\frac{1}{9}

Apply cross multiplication

x=\frac{9\times 4}{3}\\x=\frac{36}{3} \\x=12hours
