Slope formula: m = 
(Knowing that m represents the slope)
Substitute (1,0) for (x1,y1), and (-1,-3) for (x2,y2)
Slope of the line of (1,0) and (-1,-3) is:
m = 
= 
= 
(Simplify)
Slope of the line of (1,0) and (-1,-3) is
To find equivalent numbers you multiply the top and bottom by the same number. Examples are: 2/10 (by 2), 3/15 (by 3), 4/20 (by 4), etc.
1 * 9 = 9
------------
5 * 9 = 45
So another is 9/45
hope it helps!
17, 21, 25, etc. because when you divided 4 by any of these numbers you will get your answer with a remainder of 1. For example, 17/4 is 4 R.1 because 4 times 4 is 16, then you will have one left over. (At my school you always go to a decimal not a remainder)
Let's solve your equation step-by-step.
−(1+7x)=6(−7−x)+36
Step 1: Simplify both sides of the equation.
−(1+7x)=6(−7−x)+36
−7x+−1=(6)(−7)+(6)(−x)+36(Distribute)
−7x+−1=−42+−6x+36
−7x−1=(−6x)+(−42+36)(Combine Like Terms)
−7x−1=−6x+−6
−7x−1=−6x−6
Step 2: Add 6x to both sides.
−7x−1+6x=−6x−6+6x
−x−1=−6
Step 3: Add 1 to both sides.
−x−1+1=−6+1
−x=−5
Step 4: Divide both sides by -1.
