Find the equation of a line that has a slope of 1/2 and passes through the origin.
omeli [17]

Step-by-step explanation:

The equation of a line with slope m and y-intercept b is y = m x + b.  

This line goes through the point ( 0 ,0 ), so the y-intercept is zero.

We are given the slope as − 2 / 3.

The equation of the line is y= – 2 / 3 x + 0 = – 2 / 3 x

y = – 2 / 3 x

Can someone also explain how to get the answer thank u
goblinko [34]

Answer:

m = -\frac{194}{3}

Step-by-step explanation:

I'm assuming you are trying to find m. In order to do so, you need to get m on one side.

Before doing that let's multiple -2 and -3m by \frac{4}{3}

256=-\frac{8}{3} - 4m

add -\frac{8}{3} to both sides

258\frac{2}{3}=-4m

I would get rid of the fraction so I'd multiply both sides by \frac{3}{1}

\frac{776}{3}*3 = 4m*3

776=-12m

divide both sides by -12m

m = -\frac{776}{12}

which can be simplified to

m = -\frac{194}{3}

ALL UNLESS THAT \frac{4}{3} IS A POWER

5.708 x 10v-8 in standard form<br><br> Calculator won’t answer it..
Troyanec [42]

Hi Sebastian0113,

Your Question:

5.708 x 10^-8 in standard form

Solution:

Decimal Form:

To solve this equation just divide 5.708 by 10 8 times.

= 5.708 / 10 / 10 / 10 / 10 / 10 / 10 / 10 / 10

= 0.000000005708

5.708 x 10^-8 = 0.000000005708

Standard Form:

5.708 x 10^8

5.708 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10

= 570,800,000

Answer:

Standard Form - 570,800,000

Decimal Form - 0.0000005708
