the equation of the straight line that passes through the point with coordinates of 0,0 and 2,8. do the same for the coordinates

spin [16.1K]

Answer: Equation of a line passes through (0,0) and (2,8): $y=4x$

Equation of a line passes through (0,0) and (4,2): $y=\dfrac{1}{2}x$

Equation of a line passes through (0,0) and (2,10): $y=5x$

Step-by-step explanation:

Equation of a line passes through (a,b) and (c,d) : $(y-b)=\dfrac{d-b}{c-a}(x-a)$

Then, Equation of a line passes through (0,0) and (2,8):

$(y-0)=\dfrac{8-0}{2-0}(x-0)\\\\\Rightarrow\ y=4x$

Equation of a line passes through (0,0) and (4,2):

$(y-0)=\dfrac{2-0}{4-0}(x-0)\\\\\Rightarrow\ y=\dfrac{1}{2}x$

Equation of a line passes through (0,0) and (2,10):

$(y-0)=\dfrac{10-0}{2-0}(x-0)\\\\\Rightarrow\ y=5x$

Please help with 3 questions and show all work!!!

Question 1:
Since the triangles are congruent, we know that QS = TV
This means that
3v + 2 = 7v - 6
Subtract both sides by 2
3v = 7v - 8
Subtract 7v from both sides
-4v = -8
Divide both sides by -4
v = 2
Plug this value back into 3v + 2 and you get 8.
QS = 8
Since the triangles are congruent
QS = 8 AND TV = 8

Question 2:
So we know that AC = AC because that's a shared side.
It's also given that BC = CD.
In order for two triangles to be congruent by SAS, the angle between the two sides must be congruent.
That means angle C must be congruent to angle C from the other triangle.

Question 3:
We know that AC = AC because it's a shared side.
We also know that angle A from one triangle is equal to angle C from the other.
However, for a triangle to be congruent by SAS, the congruent angle must be between two congruent sides.
In order for us to prove congruence by SAS, AD must be congruent to BC.

Have an awesome day! :)
