  • Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept

So remember that <u>parallel lines have the same slope,</u> while <u>perpendicular lines have slopes that are negative reciprocals to each other.</u> But first, we have to find out the slope of the original equation. The easiest method to find the slope is to convert this standard form equation to slope-intercept form.

Firstly, subtract 6x on both sides of the equation: -4y=-6x-3

Next, divide both sides by -4 and your slope-intercept form is y=\frac{3}{2}x+\frac{3}{4}

Now, looking at our slope-intercept form we see that the slope of the original equation is 3/2. Using what we know about parallel and perpendicular lines, <u>the slope of a parallel line is 3/2 and the slope of a perpendicular line is -2/3</u>

e-lub [12.9K]
This is just another way of asking "what is the volume of a sphere of 6cm"
The volume of a sphere is V= \frac{3}{4} \pi  R^{3}
The R is 3cm in this problem since the diameter is twice the radius. For a 3cm radius sphere this is 113.1cm^3

what is the equation in slope form of the line that is parallel to the given line and passes through the point (-3,1)​
viktelen [127]

Answer:

D

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate the slope of the given line using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 4) and (x₂, y₂ ) = (2, 2) ← 2 points on the line

m = \frac{2+4}{2+2} = \frac{6}{4} = \frac{3}{2}

Parallel lines have equal slopes and using (a, b) = (- 3, 1), then

y - 1 = \frac{3}{2}(x - (- 3)), that is

y - 1 = \frac{3}{2}(x + 3) ← in point- slope form

Can anybody tell me what is a stem-and-leaf plot and a example
zhannawk [14.2K]

The following examples provide some practice with stem-and-leaf plots, as well as explaining some details of formatting, and showing how to create a "key" for your plot.

<span> Subjects in a psychological study were timed while completing a certain task. Complete a stem-and-leaf plot for the following list of times: </span>

7.6,  8.1,  9.2,  6.8,  5.9,  6.2,  6.1,  5.8,  7.3,  8.1,  8.8,  7.4,  7.7,  8.2

The first thing I'll do is reorder this list. It isn't required, but it surely makes life easier. My ordered list is:

5.8,  5.9,  6.1,  6.2,  6.8,  7.3,  7.4,  7.6,  7.7,  8.1,  8.1,  8.2,  8.8,  9.2

These values have one decimal place, but the stem-and-leaf plot makes no accomodation for this. The stem-and-leaf plot only looks at the last digit (for the leaves) and all the digits before (for the stem). So I'll have to put a "key" or "legend" on this plot to show what I mean by the numbers in this plot. The ones digits will be the stem values, and the tenths will be the leaves.
