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!!!

Answer:
-x+4
Step-by-step explanation:
given that
(x^3-4x^2+7x-28)÷(x^2+7)
or
first (x^2+7) × -x = -x^3-7x
so (x^3-4x^2+7x-28) + (-x^3-7x) = -4x^2-28
agian (x^2+7)×(4) = 4x^2+28
so, (-4x^2-28) + (4x^2+28) = 0
hence the quotient is -x+4
Answer:
Step-by-step explanation:
they give you points that are variable instead of numbers
P1=(a,0)
P2=(0,b)
also a and b are the length of that side of the triangle
so
MP =
then what ever a and b are.. you're set
to show your work you could use the distance formula which will give you the same thing above
MP =
MP =
which is just the formula above :)
