Anyone who has a general idea of how to do these please help
1 answer:
6. slopes of perpendicular lines are negative reciprocals of each other. Therefore if CD is 
, the slope of AB will be - 
7. Note that the y intercept of the line is (0,8). Also note that another point on the line is (3,4). Now use these two points to find the slope
Moving from point (0,8) to (3,4), we go down 4 and to the right 3. Therefore, the slope is - 
. At this point, we can just substitute into slope intercept form of a line: y = mx + b or 
8. First find the slope of the line containing the points (-2,-3) and (2,5): The slope is
Now substitute that slope and the point (-4,5) into point slope form of the a line. You get:
y - 5 = 2(x + 4)

To answer this, we will need to know:
• The slope of the equation we are trying to get
• The point it passes through using the
First, we will need to find the slope of this equation. To find this, we must simplify the equation
into 
form. Lets do it!
=
(Subtract 3x from both sides)
=
(Divide both sides by 5)
The slope of a line perpendicular would have to multiply with the equation we just changed to equal -1. In other words, it would have to equal the negative reciprocal.
The negative reciprocal of the line given is
.
Now that we know the slope, we have to find out the rest of the equation using the slope formula, which is:
Substituting values, we find that:
By simplifying this equation to slope-intercept form (By cross-multiplying then simplifying), we then get that:
, which is our final answer.
Thank you, and I wish you luck.

Hey there!
The answer to your question is
Given:
First, we distribute the negative sign to both terms (
) This would make the
negative and the
positive, so we have:
Add them together and we get:
Have a nice day!
