Answer:
x + 5y = 7 or y = -⅕x + 1⅖
Step-by-step explanation:
First, find the rate of change [slope]:
-y₁ + y₂\-x₁ + x₂ = m
Then use the Point-Slope Formula since we are given points. Now, according to this formula, all negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs. It does not matter which one you choose:
y - y₁ = m(x - x₁)
y - 1 = -⅕(x - 2)
y - 1 = -⅕x + ⅖
+ 1 + 1
_______________
y = -⅕x + 1⅖ >> Line in <em>Slope-Intercept</em><em> </em><em>Form</em>
If you want it in Standard Form:
y = -⅕x + 1⅖
+⅕x +⅕x
___________
⅕x + y = 1⅖ [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅕x + y = 1⅖]
x + 5y = 7 >> Line in <em>Standard Form</em>
__________________________________________________________
y - 2 = -⅕(x + 3)
y - 2 = -⅕x - ⅗
+ 2 + 2
______________
y = -⅕x + 1⅖
y = -⅕x + 1⅖
+⅕x +⅕x
___________
⅕x + y = 1⅖ [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅕x + y = 1⅖]
x + 5y = 7 >> Line in <em>Standard Form</em>
** You see? I told you that it would not matter which ordered pair you choose because you will always get the exact same result!!!

I = PRT
Interest = ?
Principal = $300
Rate = .08
T = 5 years
300(.08)(5) = $120
Interest = $120
So, he pays $300 + $120 in interest = $420
Answer:
12
Step-by-step explanation:
12 is the (GCF) of 36x and 12x because 12 is the biggest # that can go into both 36 and 12.
