The slope of the line below is -2. Use the coordinates of the labeled point to find the point-slope equation of the line. (4, -6

r-ruslan [8.4K]

Answer:

The point-slope equation of the line is $y = -2x +2$ or $2x+y = 2$

Solution:

Let us assume that the slope is m and the y intercept of the line is b

Hence, $y=m x+b$ --------- (i)

y intercept means we need to find the value of y when x is 0

Here the line passes through point (4,-6) and slope m = (-2)

Now putting the point (4,-6) in equation (i) we get,

$\Rightarrow-6 = m\times4 +b$

$\Rightarrow-6 = (-2)\times4 +b$

$\Rightarrow-6 = -8 +b$

$\Rightarrow-6+8 =b$

$\Rightarrow b = 2$

So, the equation of the line will be will be $y = -2x +2$ or $2x+y = 2$

4. These polygons are similar, but not drawn to scale. Find the value of x.

Dafna11 [192]

Answer

x=10

Step by step explanation:

It is a dilation to you would divide the known sides with each other.

8/2=4

16/4=4

So, you would then multiply 2.5 by 4 which would get you 10

preetty sure this is it, if its wrong then im sorry

Write the equation that represents the line that goes through the point (5, -7) and has slope m=-3

RUDIKE [14]

Answer:

y = -3x + 8

Step-by-step explanation:

Given :-

Point on line = (5, -7)

Slope (m) = -3

To find :-

Equation of line

Solving :-

Using point-slope form of equation,

y - y₁ = m(x - x₁)

y + 7 = -3(x - 5)

y + 7 = -3x + 15

Solution :-

y = -3x + 8
