1. slope of the given line = 1/5
    the equation is 
    (y-2)/(x-(-2))=1/5
    x+2=5y-10
    x-5y+12=0

2. slope of the given line = -1/6
    the equation is
    (y-9)/x=6
    y-9=6x
    y=6x+9

Question 1 (1 point)<br> Which equation can be represented by a graph with a vertex at (1,3)?
madam [21]

Answer:

See explanation

Step-by-step explanation:

You have not provided the options to help us give you a specific answer.

If a quadratic function is written in the form

f(x) = a {(x - h)}^{2}  + k

Then (h,k) is the vertex, and 'a' is a constant.

For instance

f(x) = 5 {(x - 1)}^{2}  + 3

has vertex at (2,3).

Also, an absolute function in the form

g(x) = a  |x - h|  + k

has vertex at (h,k).

This means

g(x) =   |x - 1|  + 3

also has vertex at (1,3).

I hope this explanation is helpful.
