Y+5=2(x+1) find x and y intercepts
Andrej [43]

The x and the y intercept are x = 1.5 and y = -3

<h3>How to determine the x and the y intercept?</h3>

The linear equation is given as:

y + 5 = 2(x + 1)

Set x to 0 to determine the y-intercept.

So, we have:

y + 5 = 2(0 + 1)

This gives

y + 5 = 2

Evaluate

y = -3

Set y to 0 to determine the x-intercept.

So, we have:

0 + 5 = 2(x + 1)

This gives

5 = 2(x + 1)

Evaluate

x = 1.5

Hence, the x and the y intercept are x = 1.5 and y = -3

The coordinate plane shows Line A B.<br> What is the length of the line segment?
Lemur [1.5K]

Answer:

AB = 13 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 ) = B(- 5, 12) and (x₂, y₂ ) = A (0, 0)

d = \sqrt{(0+5)^2+(0-12)^2}

   = \sqrt{5^2+(-12)^2}

   = \sqrt{25+144}

   = \sqrt{169}

   = 13
