Graph the line with slope 1/2 passing through the point (5, - 1)
True [87]

Answer:

<u><em>The equation is y = (1/2)x + - 3.5</em></u>

Step-by-step explanation:

We look for an equation with the form y = mx + b, where m is the slope and b the y-intercept.

We're given the slope, (1/2) which we can use for m:

y = (1/2)x + b

We are told the line goes through (5,-1).  We need a value of b that will move the line to include this point.  Do that by substituting the values:

 x = 5, and y= -1

y = (1/2)x + b

-1 = (1/2)*5 + b

-1 = (2.5) + b

- 3.5 =   b

<u><em>The equation is y = (1/2)x + - 3.5</em></u>

See the attached image.

Applied to the graph of y= 1/x
Bess [88]

Answer:

y = -3/(x-4) - 2

Step-by-step explanation:

3*y(x) vertically stretches <em>y</em> by a factor 3

-y(x) reflects <em>y</em> over x-axis

y(x-4) translates <em>y</em> 4 units to the right

y(x) - 2 translates <em>y</em> 2 units down

Applied the transformations we get:

y(x) = 1/x → 3/x → -3/x → -3/(x-4) → -3/(x-4) - 2
