First, find the slope (m) = 
= 
= 
= 
Now plug in ONE of the points and the slope into the point-slope equation:
y - y₁ = m(x - x₁); where (x₁, y₁) is the chosen point.
y - 5 = (x - 1) (I used (1,5) as the chosen point)
3(y - 5) = x - 1
3y - 15 = x - 1
3y -14 = x
-14 = x - 3y → x - 3y = -14
Answer: x - 3y = -14
Answer:
y=3x-2
Step-by-step explanation:
Since we already know the slope, all we need to find is the y-intercept
The equation for a line is:
y=mx+b where m is the slope and b is the y-intercept. x and y are the x and y coordinates. We can use the numbers given in the problem and plug them into the equation...
y=mx+b
-8=3(-2)+b
-8=-6+b
b=-2
So the equation would be...
y=3x-2
Answer:
$27,025
Step-by-step explanation:
I don't know how to do this, so, yeah.
11,500 x 15%
= 1,725
1,725 x 9
= 15,525
15,525 + 11,500
= 27,025
Answer:
<em>Value of x = 25</em>
Step-by-Step Explanation:
~ Knowing that, in a right triangle ~
sin(40-x)=cos(3x) ⇒
sin(40-x)=sin(90-3x) ⇒
40 - x = 90 - 3x ⇒
40 - x +3x=90 - 3x +3x =>
40+2x=90 =>
2x=50 =>
x = 25
<em>Now it is proven to be that,</em>
<em>x = 25</em>
The y intercept is 3 because that is where the point aligns to the axis
