Select the equation that represents a line with a slope of 2 and that contains the point (1, -5).

kondor19780726 [428]

To get the equation of a line, you can use the following:

y - y1 = m (x - x1)

Where:

m is the slope (2)
y1 is the y coordinate of a point (1, -5)
x1 is the x coordinate of the same point (1, -5)

Just substitute in the values:

y - y1 = m (x - x1)

y - (-5) = 2(x - 1) <em>( - - 5 = + 5 )</em>

y + 5 = 2(x - 1)

_________________________

Answer:

B. y + 5 = 2(x - 1)

Passing through (2, - 2) and perpendicular to the line whose equation is y= 5x+2

jonny [76]

Step-by-step explanation:

Hey there!!!

Here,

Given, A line passes through point (2,-2) and is perpendicular to the y= 5x+2.

The equation of a straight line passing through point is,

$(y - y1) = m1(x - x1)$

Now, put all values.

$(y + 2) = m1(x - 2)$

It is the 1st equation.

Another equation is;

y = 5x +2........(2nd equation).

Now, Comparing it with y = mx + c, we get;

m2=5

As per the condition of perpendicular lines,

m1×m2= -1

m1 × 5 = -1

Therefore, m2= -1/5.

Keeping the value of m1 in 1st equation.

$(y + 2) = \frac{ - 1}{5} (x - 2)$

Simplify them.

$5(y + 2) = - x + 2$

$5y + 10 = - x + 2$

$x + 5y + 8 = 0$

Therefore the required equation is x+5y+8= 0.

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point A(2, 125)

Point B(98, 15)

<u>Step 2: Identify</u>

A(2, 125) → x₁ = 2, y₁ = 125

B(98, 15) → x₂ = 98, y₂ = 15

<u>Step 3: Find distance </u><em><u>d</u></em>

Substitute in coordinates [Distance Formula]: $\displaystyle d = \sqrt{(98-2)^2+(15-125)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(96)^2+(-110)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{9216+12100}$
[√Radical] Add: $\displaystyle d = \sqrt{21316}$
[√Radical] Evaluate: $\displaystyle d = 146$
