The linear equation y=3x−5y=3x−5 y equals 3 x , minus 5 is in what form.

1 answer:

4 0

I must make some assumptions here about what you may have meant by your "linear equation y=3x−5y=3x−5 y equals 3 x , minus 5."

You've written "y=3x-5" three times on the same line of type. Why is that?

Let's change what you've typed to the following:

linear equation y=3x−5

separate linear equation y equals 3x minus 5, or y=3x-5

Please go back and ensure that you have copied down this problem precisely as it was originally presented. Be careful not to duplicate info (as you did in typing "y=3x-5," followed by "y equals 3 x , minus 5."

y = 3x - 5 is, as you say, "a linear equation." The slope of this line is 3 and the y-intercept is (0, -5).

As to form: This is a "slope-intercept equation of a straight line."

Other forms include "General form of the equation of a straight line," "Point-slope form."

The cone and the cylinder below have equal surface area. True or false.

WARRIOR [948]

Answer:

False

Step-by-step explanation:

The surface area of the cone is

$V=\pi r^2 +\pi rl$

$SA=\pi r^2 +\pi\times r\times 2r$

$SA=\pi r^2 +2\pi\times r^2$

$SA=3\pi r^2$

The surface area of the cylinder is:

$SA=2\pi r^2 +2\pi rh$

$SA=2\pi r^2 +2\pi\times r\times r$

$SA=4\pi r^2$

Find the equation (in terms of x) of the line through the points (-2,1) and (3,5)

masha68 [24]

9514 1404 393

Answer:

y = 4/5x +13/5

Step-by-step explanation:

The slope is given by the formula ...

m = (y2 -y1)/(x2 -x1)

m = (5 -1)/(3 -(-2)) = 4/5

The y-intercept is given by the formula ...

b = y -mx . . . . for any point (x, y)

b = 1 -(4/5)(-2) = 1 +8/5 = 13/5 . . . . using the first point

So, the equation is ...

y = mx +b

y = 4/5x +13/5

_____

Additional comment

If you have a bunch of these to do, you may want to make a spreadsheet with the formulas built in. Then you can type in the two points and have it spit out the m and b for your equation. Even if you don't use it to do the work, you can use it to check the work.
