(x-4)^2-19=y
you first add the three to the other side, then add 16 on both sides, make the left side x-4 squared, and lastly you subtract 19 from both sides.
<span>So the question is what does the point (-3, -5) correspond to on the graph of the function. If we have a point on a graph in the Cartesian coordinate system then that point consists of coordinates (x, y). In other words, y=f(x) and x so (x, f(x)) where x is a x-coordinate and y=f(x) is y-coordinate. So if we have a point (-3, -5) the corresponding coordinates are x=-3 and y=f(x)=-5. So it must be true that y=f(-3)=-5. So the correct answer is a. f(-3)=-5.</span>
The slope-intercept form for the line with slope -5 and y-intercept 3 is,
y= -3x+5.
What is the slope-intercept form of a line?
The conventional form Ax + By = C and y= mx + b have been used to describe linear equations. The slope-intercept form y = mx + b will now be the focus of our attention.
You can write a linear function using the slope of the line and the y-intercept in the slope-intercept form.
y=mx+b
Where b is the y-intercept and m is the slope.
A straight line's slope-intercept equation is written as y=mx+b, where m denotes the slope and b is the y-intercept.
In this case, m=3 and b=5 and y=3x+5 y=3x+5 is the necessary equation.
Hence,The slope-intercept form for the line with slope -5 and y-intercept 3 is,
y= -3x+5.

Given:
The number of ribbons it can sell each week, x, is related to the price p per ribbon by the equation:
To find:
The selling price if the company wants the weekly revenue to be $1,600.
Solution:
We know that the revenue is the product of quantity and price.
We need to find the value of p when the value of R is $1600.
Divide both sides by 100.
Splitting the middle term, we get
Using zero product property, we get
or 
or 
Therefore, the smaller value of p is $2 and the larger value of p is $8.
