2x-y=-1 in slope intercept form

Mathematics

PolarNik [594]3 years ago

Answer:

<h2>y = 2x + 1</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

We have the equation of a line in a standard form.

Convert to the slope-intercept form:

2x-y=-1         <em>add y to both sides</em>

2x-y+y=-1+y

2x=-1+y            <em>add 1 to both sides</em>

2x+1=-1+1+y

2x+1=y\to y=2x+1

Answer:y=2x+1

I believe. I could be wrong. But I think im right

Step-by-step explanation:

2x-y=-1

-2x -2x

(-1)-y=-1-2x(-1)

y=2x+1

Lydia graphed ΔXYZ at the coordinates X (0, −4), Y (2, −3), and Z (2, −6). She thinks ΔXYZ is a right triangle. Is Lydia's asser
katrin [286]

Answer:

Option (4)

Step-by-step explanation:

Vertices of the triangle are X(0, -4), Y(2, -3) and Z(2, -6).

Slope of XY (m_{1}) = \frac{y-y'}{x-x'}

                            = \frac{-3+4}{2-0}

                     (m_{1}) = \frac{1}{2}

Similarly, slope of XZ (m_{2}) = \frac{-6+4}{2-0}          

                                   (m_{2}) = (-1)

m_{1}\times m_{2}=-\frac{1}{2}

Which should be (-1) if XY and XZ are perpendicular to each other.

Now we can say that XY and XZ are not perpendicular.

Therefore, Lydia's assertion that ΔXYZ is a right triangle is not correct.

Option (4) will be the answer.

Answer:

  \dfrac{2x}{3a^2}

Step-by-step explanation:

\dfrac{3a^4b}{2x}\cdot\dfrac{4x^2}{9a^6b}=\dfrac{3\cdot 4}{2\cdot 9}a^{4-6}b^{1-1}x^{2-1}=\dfrac{2x}{3a^2}

The applicable rules of exponents are ...

  • (a^b)(a^c) = a^(b+c)
  • a^-b = 1/a^b
