When given <br> Slope= -6/5<br> Y-intercept= 2 <br> What is this in Point-Slope form?
marishachu [46]

-------------------------------------------------------------------------------------------------------------

Answer:  \textsf{y - 2 = -6/5(x - 0)}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{Slope = -6/5, Goes through (0, 2)}

Find:  \textsf{The equation in point-slope form}

Solution: We need to take the values that were given to us and plug them into the point-slope form.  It doesn't seem like the problem is asking for anything more than that so we will leave it at that.

<u>Plug in the values</u>

  • \textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}
  • \textsf{y - 2 = -6/5(x - 0)}

Since the problem is just asking for the equation in point-slope form the final expression would be y - 2 = -6/5(x - 0).

A rectangle is 3 times as long as it is wide. the perimeter is 16 feet. find the dimensions ​
astraxan [27]

Answer:

Width = 2 feet

Length = 6 feet

Explanation:

Variables:

Perimeter = p

Length = l

Width = w

Equation:

2w + 2l = p

It is given that:

l = 3w

and

p = 16 feet

With this information, we can rewrite the equation (substitute)

2w + 2(3w) = 16

Simplify

2w + 6w = 16

Add

8w = 16

Divide both sides of the equation by 8

Width = 2 feet

Length = 3(w) = 3(2) = 6 feet

Hope this helps :)
