Find the distance between the point (3, 5) and a line with the equation 5 x - 3 y + 10 = 0

timama [110]

The distance between the point (3, 5) and a line with the equation 5x – 3y + 10 = 0 will be 10 / √(34) units.

<h3>What is the distance between a point and a line?</h3>

Let (x₁, y₁) be the point and ax + by + c = 0 be the line.

Then the distance between a point and a line will be

$\rm d = \dfrac{|ax_1 + by_1 + c|}{\sqrt{a^2 + b^2}}$

The point (3, 5) and a line with the equation 5x – 3y + 10 = 0.

Then the distance between them will be

$\rm d = \dfrac{|5 *3 - 3 *5 + 10|}{\sqrt{5^2 + (-3)^2}}\\d = \dfrac{10 }{\sqrt{34}} \ units$

Please help I don't understand

Mars2501 [29]

Answer:

3. 3:5

4. 4:1

Step-by-step explanation:

Just ratios I believe, myb if it's wrong but that should be it.

Since 3 & 5 aren't divisible by anything the scale factor is just 3:5.

Since 24 & 6 are divisible by a common number, being 6, you'd divide 24:6 & get a scale factor of 4:1.
