1. To be able to write the equation of the line, you want to be able to find the slope first. To do so, rearrange the given equation x+2y=2 into slope-intercept form, which is y=mx+b

First subtract x from both side, which will give us 2y=2-x. Rearrange this to get 2y= -x+2. Then, divide both sides by 2. This will give us y= -1/2x+1

2. Now that you have the equation, look for the slope in the new equation; this will be the m value. In this case, the slope is -1/2. Since we are looking for a line that is perpendicular, we have to change the slope so that it is the opposite reciprocal. The opposite reciprocal of -1/2 is 2, so the slope of the equation we want to find is 2.

3. Next, all we have to do is plug the given ordered pair (-5, -6) and the slope that we found (m=2) into the point-slope equation, which is $y-y_{1} = m(x-x_{1} )$

That will give us:

y+6 = 2(x+5)

4. Now, solve this equation.

y+6 = 2(x+5) --> distribute the 2 inside the parentheses

y+6 = 2x + 10 --> subtract 6 from both sides

y= 2x +4

Which inequality is true when R = 4.6

Nookie1986 [14]

Answer:

A. 3R > 14

Step-by-step explanation:

Here R = 4.6

Now we have to check each options and find which is true.

3R > 14

Dividing both sides by 3, we get

R > 14/3

R > 4.67

Which is true.

All other options are not true.

R + 32 >

R > -32 is not true.

R - 12 < -8

R < +4 is not true.

R/3 < 1

R < 3 is not true.

Hope this will help you.
