In your mind, you could think 100% more is 200% and 50% of that is another 100% so 200% increase. Let's see on paper. x will be her current hair length. 

<span>x + x + .5(x + x) </span>

<span>x + x is simply her hair length doubling. This is when it grew 100% longer. Then, from that, we have 50% more, so we have to add 50% of the x + x. </span>

<span>2x + .5x + .5x </span>
<span>3x </span>

<span>Subtract our starting length. </span>

<span>3x - x = 2x </span>

<span>The difference is 2 hair lengths, or 200% her original length of hair.</span>

What is the equation of the line graphed below? (3,-1) A. y=1/3x B. y=x C. y=-3x D. y=- 1/3x
Rzqust [24]

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The correct option is A.

<h3>What is the equation of a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is constant.

The graph of the question is mentioned below.

If we look the function given below then it can be observed that the given graph is linear. Also, the line passes through (0,0) and (3,1).

The slope of the line is,

Slope, m = (1-0)/(3-0) = 1/3

The y-intercept of the line is at the origin. Thus, the equation can be written as,

y = (1/3)x + 0

y = (1/3)x

Hence, the correct option is A.

12. Find the slope and y-intercept of the line. y= 1/5x-8
eduard

Hello and Good Morning/Afternoon:

<u>Let's take this problem step-by-step</u>:

<u>What does the problem want us to find:</u>

  • slope
  • y-intercept

<u>Let's gather the information</u>:

  ⇒ the information given: y = 1/5 x - 8

        ⇒ the line is in <u>slope-intercept form</u>

            ⇒ means:

                     ⇒ coefficient in front of 'x' is the slope

                     ⇒ constant is the y-intercept

  • slope is 1/5
  • y-intecept is -8

<u>Answer:</u>

  • <u>Slope is 1/5</u>
  • <u>y-intercept is -8</u>

<u></u>

Hope that helps!
