What equation in slope-intercept form represents the line that passes through

gregori [183]

Answer:

So, equation in slope-intercept form that represents the line that passes through the points (1,3) and (2,5) is y=2x+1

Step-by-step explanation:

We need to write equation in slope intercept form that represents the line that passes through the points (1,3) and (2,5)

The standard equation of slope-intercept form is: y= mx+b

where m is the slope of the lines and b is the y-intercept.

To make the equation we need to find slope (m) and y-intercept (b)

Find Slope

The formula to find slope m is: $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

We have $x_{1}=1, x_{2}=2, y_{1}=3\ and \ y_{2}=5$

Putting values in the formula to find slope

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\m=\frac{5-3}{2-1}\\m=\frac{2}{1}\\m=2$

So, value of slope m is m=2

Find y-intercept

Using formula of slope-intercept formula we can find b

y=mx+b

Using point (1,3) (where x=1 ,y=3) and slope m=2

$3=2(1)+b\\3=2+b\\b=3-2\\b=1$

So, value of y-intercept b is: b=1

Required equation in Slope Intercept Form

We have slope m = 2 and y-intercept b=1

$y=mx+b\\y=2x+1$

So, equation in slope-intercept form that represents the line that passes through the points (1,3) and (2,5) is y=2x+1

Sarah rolled a number cube numbered 1 to 6. The table below shows the results of rolling the cube 50 times. Use the results in t

cricket20 [7]

If P(3) stands for the probability of the number 3 getting rolled, since 3 was rolled 5 times (as shown on the graph) out of 50 (as mentioned in the question), the experimental probability would be: 5/50, which when simplified, is 1/10

0.333333333 to the nearest thousand

ruslelena [56]

Based on the explanation below, rounding 0.333333333 to the nearest thousand will give us 0.333.

<h3>How do we round a number to the nearest thousand?</h3>

The number 0.333333333 can be rounded to the nearest thousand as follows:

The first 3 after the decimal point is referred to as tenths.

The second 3 after the decimal point is referred to as hundredths.

The third 3 after the decimal point is referred to as thousandths, and this is our target.

Since the fourth 3 after the decimal point is less than 5, this implies that we are going to round it down and it will not change the third 3 after the decimal point.

Therefore, we have:

Rounding 0.333333333 to the nearest thousand = 0.333
