Answer: y + 7 = -2/3 (x - 1 )

Step-by-step explanation:

The equation of a line in point - slope form is given as :

y-y_{1} = m(x-x_{1} )

Where m is the slope and (x_{1} , y_{1}) is the given point

substituting the values into the formula , we have:

y - (-7) = -2/3 ( x - 1)

y + 7 = -2/3(x - 1 )

2x + 4 ( -6x + 12) = -84<br><br> What is X?
katrin [286]
2x + 4(-6x + 12) = -84

2x - 24x + 48 = -84

-22x + 48 = -84

-22x = -84 - 48

-22x = -132

x = -132/-22

x = 6

hope this helps, God bless!

What is the image point of (-4, 8) after a translation right 4 units and up 2 units?
Vitek1552 [10]

Given:

Point = ( -4,8).

To find:

The image point of (-4, 8) after a translation right 4 units and up 2 units.

Solution:

We know that, if a figure translated 4 units right and 2 units up, then the rule of translation is

(x,y)\to (x+4,y+2)

The point is (-4,8).

Putting x=-4 and y=8, we get

(-4,2)\to (-4+4,8+2)

(-4,2)\to (0,10)

Therefore, the image of point (-4,8) is (0,10).
