Write in slope intercept form an equation of the line that passes through the given points
Tpy6a [65]

Answer:

The desired equation is y = x + 8.

Step-by-step explanation:

As we move right from (-2,6) to (4,12), x increases by 6 and y also increases by 6.  Thus, the slope, m, m = rise / run, is m = 6/6, or just m = 1.

Start with the slope intercept form y = mx + b.  Since m = 1, we now have y = x + b.  Subbing 4 for x, 12 for y, we can find b:  12 = 4 + b.  Thus, b = 8.

The desired equation is y = x + 8.

The marks obtained by 10 student in a test are as follows: 3,7,6,2,8,5,9,1,4 and 10. find the mean mark​
alekssr [168]

Answer:

5.5

Step-by-step explanation:

Mean:

The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values. The formula for the mean of a population is

\mu = \frac{{\sum}x}{N}

The formula for the mean of a sample is

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

Both of these formulas use the same mathematical process: find the sum of the data values and divide by the total. For the data values entered above, the solution is:

\frac{55}{10} = 5.5

Write an equation in slope intercept form for the graph shown.
horsena [70]

Answer:

y = -2x + 3

Step-by-step explanation:

The basic format of slope intercept form is y=mx+b.

y = any "y" value

m = the slope (or rate of change) of the line

x = any "x" value

b = the y-intercept (or the value of "y" when "x" is equal to 0)


Next, look at the graph to see what you know. You know that "y" and "x" will not have a specific value because they are constantly changing as you move along the line. So, y = y and x = x.

The "m" value can be determined by looking at the points where the line crosses on the graph. The first point you can look at is (0,3) because the x-value is 0 and the y-value is 3. The next point you can use is (1,1) because the x-value is 1 and the y-value is also 1. You would then calculate the slope by using the "rise divided by run" tactic. The line goes down by 2 (so the rise is -2). The line "runs" by 1 (so the run is 1). The rise divided by the run is -2. So m = -2.

The b value can be calculated by looking at what "y" equals when x = 0. When x = 0 on this graph, y = 3. So b = 3.

After filling in all of your known information, you should get y = -2x+3 .
