Select the equation of the line to the equation y=-4x-6 and that passes through the point (1,2)
omeli [17]
I don't see a list of options, but I know that the answer is y = -4x + 6.

Point - Slope Form: y - y₁ = m(x - x₁)

y - 2 = -4(x - 1)

y - 2 = -4x + 4
  + 2          + 2

What is the vaule of m in this equation 188 = m + 80
Crazy boy [7]

Explanation:

First, switch sides of an equation.

m+80=188

Then, you subtract by the 80 from both sides of an equation.

m+80-80=188-80

And finally, simplify and subtract the numbers.

188-80=108

\boxed{m=108}

Hope this helps!

Thank you!

Have a great day!

Answer:

  y = -3x^2 -9x +30

Step-by-step explanation:

When a polynomial has a zero at x=p, it has a factor of (x -p). The factors of your quadratic are ...

  f(x) = (x +5)(x -2)

At the point x=3, the value of this product is ...

  f(3) = (3 +5)(3 -2) = (8)(1) = 8

In order for that value to be -24, it needs to be multiplied by a scale factor of -3. The quadratic you want is ...

  y = -3(x +5)(x -2)

  y = -3x^2 -9x +30 . . . . . standard form
