Answer:

The equation of the line parallel to y=4/3x−4 that passes through (-4,6) is y=4/3x−10/3 .

The equation of the line perpendicular to y=43x−4 that passes through (-4,6) is y=−3/4x+10 .

Step-by-step explanation:

Parallel means equal slopes. Hence, the slope of the line parallel to y=4/3x+3 is 4/3 . We know our slope and we know a point. We can therefore use point-slope form to determine the equation of the new line.  

y−y1=m(x−x1)  

y−6=4/3(x−4)  

y−6=4/3x−16/3  

y=4/3x−7/3  

The equation of the line parallel to y=4/3x−4 that passes through (-4,6) is y=4/3x−10/3 .

Question #2:

Perpendicular means negative reciprocal slopes. Hence, the slope perpendicular to y=4/3x+3 is y=−3/4 . We know our slope and we know a point. We can therefore use point-slope form to determine the equation of the new line.  

y−y1=m(x−x1)  

y−6=−3/4(x-4)  

y−6=−3/4x+6  

y=−3/4x+10

The equation of the line perpendicular to y=43x−4 that passes through (-4,6) is y=−3/4x+10 .

Explain this diagram.
spayn [35]

The shape that we have here is sued to show the infinite geometric progression.

<h3>What is geometric progression?</h3>

This is the sequence of numbers that has all the other values in the sequence gotten by the multiplication of a certain factor

In this question or the shape we can see that the triangle is made up of smaller other triangles embedded in it.

The area of the traingle that is in the red color is seen to have been made up of 1/3 of the total triangles that we have in the shape. This can be seen to be similar as the triangles that are represented by the green and the blue color.

Putting a  lot of triangles inside one big triangle gives up a pictorial diagram on how to add infinite amount of things up.
