The points (12, 3) and (20, 5) fall on a particular line. What is its equation in slope-intercept form?
sdas [7]

Answer:

y= ¼x

Step-by-step explanation:

<u>Slope-intercept </u><u>form</u>

y= mx +c, where m is the slope and c is the y-intercept.

\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }

Slope

=  \frac{5 - 3}{20 - 12}

=  \frac{2}{8}

=  \frac{1}{4}

Substitute the value of the slope into the equation:

y= ¼x +c

To find the value of c, substitute a pair of coordinates.

When x= 12, y= 3,

3 =  \frac{1}{4} (12) + c

3= 3 +c

c= 3 -3

c= 0

Thus, the equation of the line is y= ¼x.

lara31 [8.8K]

<em>The missing weights are:</em>

<em>2 2 2 1 11 12 12 2 24 22 24 3 37 22</em>

Answer:

Average = 12\frac{4}{7} \ lb

Step-by-step explanation:

Given

Weight of sea glass

To solve this question, we have to calculate the mean of the weight of the sea glass as follows;

Average = \frac{\sum x}{n}

Where n = number of sea glass

n = 14

So:

Average = \frac{\sum x}{n} becomes

Average = \frac{2 +2 + 2 + 1 + 11 +12 +12 +2 +24+22 +24 +3 +37+ 22}{14}

Average = \frac{176}{14}

Average = 12\frac{8}{14}

Simplify fraction

Average = 12\frac{4}{7}

<em>Hence; the weight of the sea glass would be </em>12\frac{4}{7}\ lb<em> </em><em>when evenly distributed...</em>
