Answer:

y = \frac{1}{4} x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y - 4 = \frac{1}{4} (x - 8) ← distribute

y - 4 = \frac{1}4} x - 2 ( add 4 to both sides )

y = \frac{1}{4} x + 2 ← in slope- intercept form

Help with 6 a and b please
34kurt

Answer:

a) y=\frac{50}{x}

b) y=25 when x=2

Step-by-step explanation:

y=\frac{k}{x} since y varies inversely with x.

We need to find the constant, k.

Let's use a point (x,y) on the curve.

We are given an (x,y)=(5,10):

10=\frac{k}{5}

Multiply both sides by 5:

10(5)=k

50=k.

So the equation is:

y=\frac{50}{x}

What is y when x=2?

y=\frac{50}{2}

y=25
