Create the equation of the line that passes through the point (1, -10) and is perpendicular to y=-1/3x+5
Ber [7]

Answer:

y = 3x - 13

Step-by-step explanation:

y = -1/3x + 5

Perpendicular lines have slopes that are negative reciprocals of one another

so slope of perpendicular line is 3

y = mx + b

y = 3x + b

Using (1,-10)

-10 = 3(1) + b

-10 = 3 + b

b = -13

y = 3x - 13

If the relation is a function, list the domain and range. If the relation is not a function, choose "not a function". C = {(9, 1
ICE Princess25 [194]

Answer:

<h2>Domain: {9, 8, 7, -5}</h2><h2>Range: {1, -3, 5, 3}</h2>

Step-by-step explanation:

The function is a special relationship where each input has a single output.

We have C = {(9, 1); (8, -3); (7, 5); (-5, 3)}.

It's a function:

each values of x: 9, 8, 7, -5 has one value of y: 1, -3, 5, 3.

The doimain is set os x: {9, 8, 7, -5}.

The range is set of y: { 1, -3, 5, 3}.
