45+10x = y
$45 -- stays the same no matter what so that's constant.
$10 -- this varies dependent on the number of vaccinations your dog needs, so you'd use a variable to represent the number of vaccinations (in this case I'm using variable "x").
So, for example if your dog needed 7 vaccinations, it would be: 45+10(7) = y -- answer being $115.
Sorry if I am wrong
The standard form of an equation of a line
We have the eqution in the point-slope form:
Convert it to the standard form:
multiply both sides by 4
use the distributive property
add 16 to both sides
subtract 3x from both sides
change the signs
write an eaquation that is parallel to the line y=3x-5 and passes through the point -1,2
m = 38.5
m - 3/2 = 37
m - 3/2 = 37 + 3/2
m = 38 1/2 or 38.5
(m - 3/2) * 2 = 37 *2
2m - 3 = 74
2m - 3 + 3 = 74 + 3
2m = 77
2m / 2 = 77 / 2
m = 38.5
The answer is h=-2 if you are wondering on how to find that answer negative times a positive equals a negative but negative times a negative equals a positive

Multiply each side by two to eliminate the denominator
For the equation y=3x-5, the slope is 3 and the slope of the new line will be 3 because parallel lines have the same slope. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
