Answer:

y+4 = -1/6(x-9)  point slope

y = -1/6x -2.5  slope intercept

Step-by-step explanation:

The point slope form is

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is the point

y- -4 = -1/6(x-9)

y+4 = -1/6(x-9)

Distribute to get to slope intercept form

y+4 = -1/6x +9/6

y+4 = -1/6x +3/2

Subtract 4 from each side

y+4-4 = -1/6x +3/2 -4

y = -1/6x +3/2 -8/2

y = -1/6x -5/2

y = -1/6x -2.5

Answer:

y + 4 = -⅙(x - 9)

Step-by-step explanation:

y - y1 = m(x - x1)

y - (-4) = (-1/6)(x - 9)

y + 4 = -⅙(x - 9)

What is 4 ( x+2 )=10 <br>​
Len [333]

Answer:

x= 1/2

Step-by-step explanation:

We can use Distributive property to solve this.

4(x+2)=10

4x+8=10

   -8   -8

4x= 2

4x/4= 2/4

x= 1/2

Hope this is right!

I need the answer for this exact question

Answer:

y=\frac{7}{2}x-20

Step-by-step explanation:

Let the equation of the line be y-y_1=m(x-x_1) where, 'm' is its slope and (x_1,y_1) is a point on it.

Given:

The equation of a known line is:

y=-\frac{2}{7}x+9

A point on the unknown line is:

(x_1,y_1)=(4,-6)

Both the lines are perpendicular to each other.

Now, the slope of the known line is given by the coefficient of 'x'. Therefore, the slope of the known line is m_1=-\frac{2}{7}

When two lines are perpendicular, the product of their slopes is equal to -1.

Therefore,

m\cdot m_1=-1\\m=-\frac{1}{m_1}\\m=-\frac{1}{\frac{-2}{7} }=\frac{7}{2}

Therefore, the equation of the unknown line is determined by plugging in all the given values. This gives,

y-(-6))=\frac{7}{2}(x-4)\\y+6=\frac{7}{2}x-14\\y=\frac{7}{2}x-14-6\\\\y=\frac{7}{2}x-20

The equation of a line perpendicular to the given line and passing through (4, -6) is y=\frac{7}{2}x-20.
