An equation in point slope form (2,1) and has a slope of m=2
Svet_ta [14]

Answer:

y=2x-3

Step-by-step explanation:

<em>Since we know that the slope-intercept form is </em><em>y=mx+b</em><em>, we can plug in the formula with what we already know to find b!</em>

<em>In the coordinates (2,1): </em>

  • 2 is the x
  • 1 is the y

<em>Now, we will plug these numbers in:</em>

1=2*2+b

1=4+b

b=-3

<em>Now we can rewrite the equation since we found b:</em>

y=2x-3

Hope this helped! :)

Which equation(s) represents a proportional relationship?
enyata [817]

Answer:

A and C are proportional relationships.

Step-by-step explanation:

Recall that a "proportional relationship" has no constant term.  Thus, we eliminate Answers B and D immediately.

What is the value of y?<br> y +10°<br> 50°<br> A. 500<br> B. 40°<br> C. 60°<br> ОО<br> D. 300
klasskru [66]

Answer:

B

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

y + 10 + 2y + 50 = 180 , that is

3y + 60 = 180 ( subtract 60 from both sides )

3y = 120 ( divide both sides by 3 )

y = 40 → B
