Find the distance between the points
Tasya [4]

Answer:

5 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (6, 4)

d = \sqrt{(6-2)^2+(4-1)^2}

   = \sqrt{4^2+3^2}

   = \sqrt{16+9}

    = \sqrt{25}

    = 5

Write a linear equation in slope-intercept form: 5y – 3x + 20 = 0 ​
Arturiano [62]

Slope intercept form is y = mx+ b

So in order to turn 5y-3x + 20 = 0 into Slope intercept form, all we need to do is solve for y!

Let's do it!

  • add 3x to the right side of the equation

<u>5y - 3x + 20 = 0</u>

<u>5y + 20 = 3x </u>

  • move 20 to the right side

<u>5y = 3x - 20 </u>

  • Divide both sides of the equation by 5

y = 3/5x - 4

This is our answer!

I hope I helped! Leave a comment if you have any questions or concerns
