Write the equation of the line in the form Y = MX where M is the slope.

Mathematics

Ainat [17]2 years ago

Answer:

We conclude that the equation of the line in the form y = mx + b will be:  y=\frac{1}{2}x

Step-by-step explanation:

From the given graph, taking two points

  • (0, 0)
  • (10, 5)

Important Tip:

The slope-intercept form of the line equation

y = mx+b

where

  • m represents the slope
  • b represents the y-intercept

1 of 3 steps:

Determine the slope

We need to find the slope of the line containing the points (0, 0) and (10, 5)

m=\frac{y_2-y_1}{x_2-x_1}

where m is the slope between (x₁, y₁) and (x₂, y₂)

In our case,

  • (x₁, y₁) = (0, 0)  
  • (x₂, y₂) = (10, 5)

substituting (x₁, y₁) = (0, 0) and (x₂, y₂) = (10, 5) in the slope formula

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{5-0}{10-0}

Refine

m=\frac{1}{2}

Thus, the slope of the line containing the points (0, 0) and (10, 5) is: m=\frac{1}{2}

2 of 3 steps:

Determine the y-intercept

We can determine the y-intercept by determining the value of y at x = 0.

From the graph, it is clear that at x = 0 the value of y = 0.

Thus, the y-intercept of the line is: b = 0

3 of 3 steps:

Substitute the values in the slope-intercept form

Substitute the values m=\frac{1}{2} and b = 0 in the slope-intercept form

y = mx+b

y\:=\:\frac{1}{2}x+0

y=\frac{1}{2}x

Conclusion:

Therefore, we conclude that the equation of the line in the form y = mx + b will be:  y=\frac{1}{2}x

The following are score earned by 15 college students on a 20-point math quiz. (a) calculate the mean, median, and mode scores.
Softa [21]

Answer:

(a) 12.87; 14; 18; (b) median  

Step-by-step explanation:

(a) Statistics

(i) Mean

The mean is the sum of all the data points divided by the number of points.

\begin{array}{rcl}\text{Mean} & = & \dfrac{0 + 2 + 3 + 12 + 12 + 13 + 14 + 14 + 15 + 15 + 18 + 18 + 18 + 19 + 20}{15}\\\\& = & \dfrac{193}{15}\\\\& = & \mathbf{12.87}\\\end{array}

(ii) Median

The median is the middle value in your list of observations.

0, 2, 3, 12, 12, 13, 14, 14, 15, 15, 18, 18, 18, 19, 20

Median = 14

(iii) Mode

The mode is the value that appears most often in your list of observations.

0, 2, 3, 12, 12, 13, 14, 14, 15, 15, 18, 18, 18, 19, 20

Mode = 18

(b) Most representative measure

The mean is dragged down by three low values. The median is the measure that is most representative of the data.

The histogram below shows the distribution of your data.
