Answer:
see below
Step-by-step explanation:
Starting from the point-slope equation ...
y -y1 = m(x -x1)
Solving for y gives ...
y = mx +(y1 -m·x1)
So, the slope-intercept form equation is fairly easily found:
y = mx +b . . . . where m = m, and b = y1-m·x1
This is the equation we have used for 'b' in the attached spreadsheet.
__
Of course, the formula for slope is ...
m = (y2 -y1)/(x2 -x1)
This is the equation we have used for 'm' in the attached spreadsheet. For all problems, we have used the first point. (It doesn't matter which point you use if there are two of them.)
__
The second attachment is the Google Sheets spreadsheet saved in ODS format. Most spreadsheet programs should be able to open that so you can see the formulas, if you're interested. (The gray values of m are computed using the two points. The unshaded values of m are entered by hand.)
_____
I'll write a couple of equations in each group so you can see how the spreadsheet numbers relate:
y = mx +b
1. y = 2x -7
3. y = 2/3x +4
8. y = 1/3x -5
9. y = -5/2x +4

Now we know the lengths of all three sides of the triangle and the triangle is uniquely determined. Next we calculate another its characteristics - same procedure as calculation of the triangle from the known
Answer:
9 full pitchers 4 will not be used
Step-by-step explanation:
Your answer would be y< -3/2x+1
You slope is negative because the line goes from left to right and your slope is -3/2 because it rises 3 and goes to the left 2. Remember that your slope represents your rise over your run.
Your equation is also only > and not less then or equal to because it is a dotted line.
Happy studying!
Answer:
5/3 = 1.67
Step-by-step explanation:
To find how many times larger ΔMNO is, divide the side length of 15 by the original length of 9. 15 is approximately 1.67 times the size of 9, making the scale factor 1.67 or in fraction form, 5/3.
