Slope of (0,1) and (3,0)

Marysya12 [62]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{ \frac{ - 1}{3}}}}}}$

Step-by-step explanation:

Let the points be A and B

Let A ( 0 , 1 ) be ( x₁ , y₁ ) and B ( 3 , 0 ) be ( x₂ , y₂ )

Finding the slope of the points

$\boxed{ \sf{slope = \frac{y2 - y1}{x2 - x1} }}$

$\longrightarrow{ \sf{slope = \frac{0 - 1}{ 3 - 0}}}$

$\longrightarrow{ \sf{slope = \frac{ - 1}{3}}}$

Hope I helped!

Best regards! :D

Substitution: y-2x=-6 and 5x-y=9

Dmitrij [34]

y-2x=-6 and 5x-y=9

step 1: isolate y in the first equation

y = 2x - 6

step 2: substitute the y value on the 2th equation:

5x-(2x-6)=9

step 3: solve the present equation:

5x - 2x + 6 = 9
3x = 9-6
3x = 3
x = 1

step 4: get the y value by replacing the value of x in y = 2x - 6:

y = 2*1 - 6
y = 2 - 6
y = -4

S={1, -4}

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}x=-2y+300&(1)\\3y=800-4x&(2)\end{array}\right\\\\\text{Substitute (1) to (2):}\\\\3y=800-4(-2y+300)\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\3y=800+(-4)(-2y)+(-4)(300)\\\\3y=800+8y-1200\\\\3y=8y-400\qquad\text{subtract}\ 8y\ \text{from both sides}\\\\-5y=-400\qquad\text{divide both sides by (-5)}\\\\y=80\\\\\text{Put it to (1):}\\\\x=-2(80)+300\\\\x=-160+300\\\\x=140$
