HELP PLEASE I dint understand this and I only have to 12!

Work Shown:

Two points on this line are (0,0) and (1,-6)

The slope of the line through these points can be found through the slope formula

m = (y2-y1)/(x2-x1)

m = (-6-0)/(1-0)

m = -6/1

m = -6 is the slope

The y intercept is b = 0 as this is the location on the vertical y axis where the graph crosses.

Using m = -6 and b = 0, we go from y = mx+b to y = -6x+0

This simplifies to y = -6x

y = -6x

Step-by-step explanation:

Take 2 points:

(-1,6)

(1,-6)

Find the slope:

-6 - 6/1 - - 1

-12/2 = -6

So we have the equation:

y = -6x + b

now to find b, insert one of the points from before for x and y

-6 = -6(1) + b

-6 = -6 + b

b = 0

So then we get y = -6x + 0 which we can write as y = -6x

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
