- The factors of the Jared's graph are: (x - 10), (x + 3) and (x + 9)
- The y-intercept is -13.5
- The standard equation of the function is:

<u>(a) The factors</u>
First, we write out the points where the function cross the x-axis.
The points are:



Equate the above points to 0



Hence, the factors are: (x - 10), (x + 3) and (x + 9)
<u>(b) The y-intercept</u>
This is the point where the graph crosses the y-axis.
From the attached graph, the graph crosses the y-axis at -13.5.
Hence, the y-intercept is -13.5
<u>(c) The standard form</u>
In (a), we have:



Multiply the above equations

Replace 0 with y

Hence, the standard form is:

Step-by-step explanation:

Since,

Hence,


Since,

Hence,


Y=1/2x-2 on the graph -2 would be the y intercept and x/y is slope so to find y as one you go in the middle of -2 and four
Look at the first line in the first problem.
x y
<span>–6 –6
–4 –3</span>
find the slope:
y2-y1 / x2-x1
-3+6 / -4+6
3 / 2
the slope is 3/2. now plug this into point-slope form, along with one of the ordered pairs. i'll use (-4,-3) because the numbers are smaller.
y-y1=m(x-x1)
y+3=3/2(x+4)
y+3=3/2x+6
y=3/2x+3
now do the same for the other line.
<span>x y
0 3
2 6
actually, this one's convenient, because it tells you the y-intercept is 3 (when an ordered pair has a 0 as its x coordinate, that means its on the y axis). so we just have to find the slope.
y2-y1 / x2-x1
6-3 / 2-0
3/2
the line is y=3/2x+3. it's the same line as before. that means there are infinitely many solutions, because there are an infinite amount of points where the lines "cross" each other (since they lie on top of each other).
follow the same procedure for the next problem. if the equations turn out to be the same, it has infinite solutions. if the two lines have the same slope but different intercepts, that means they're parallel, and have no solution since the lines will never intersect. if the lines have different slopes, they will have one solution. and it makes no sense for lines to intersect at two different points, so you can ignore that option altogether.
hope this helps

The probability of not spinning an even number should be two out of three or 2/3. because there is only 1 even number (2).
