The equation y - 2/3= 2x(x-1/4) is written in point-slope form. What is the equation in slope-intercept form?
A y = negative 2x - 1/6
B y = negative 2 x + 7/6
C y = negative 2 x + 5/12
D y = negative 2x - 11/12

Respuesta :

A linear equation in point-slope is written as:

y - h = a*(x - k)

While the slope-intercept form is:

y = a*x + b

where a is the slope and b is the y-intercept.

We will find that the correct option is B: y = -2*x + 7/6

We start with:

y - 2/3 = -2*(x - 1/4)

And we want to rewrite this in the slope-intercept form.

First, we can distribute the product at the right:

y - 2/3 = -2*x + 2/4

Now we can add 2/3 in both sides to get:

y = -2*x + 2/4 + 2/3 = -2*x + 6/12 + 8/12

y = -2*x + 14/12

Simplifying the y-intercept we get:

y = -2*x + 7/6

Then the correct option is B: "-2*x + 7/6"

Solution:

Note that:

  • Given equation: y - 2/3 = -2(x - 1/4)

Simplify the given equation to obtain your answer in slope intercept form.

  • y - 2/3 = -2(x - 1/4)
  • => y - 2/3 = -2x + 2/4
  • => y = -2x + 2/4 + 2/3
  • => y = -2x + 6/12 + 8/12
  • => y = -2x + 14/12

14/12 simplifies to 7/6.

  • => y = -2x + 7/6

Option B is correct.
