And explain

Points D, E, and F are on a line. The coordinate of D is -3, the coordinate of E is 1, and the coordinate of F is 9. Line AB intersects line segment EF at C. If line AB is a bisector of EF, what is...

If you have the points (-2,4) (0,4) (2,0) (2,-2) (0,2) (-2,2), how can you find the perimeter? I've been on this for hours now and nothing on the internet seems to understand it.

HJ = 8x-3 JK = 12x-5 KH = 112

HJ = 3(x+2) JK = 3x-4 KH = 44

I'm not sure what the s is. and i don't know what it means by perpendicular

3 distinct lines contained within a plane separate the plane into distinct regions. How many possible distinct regions of the plane may be separated by any 3 such lines?

Consider the triangle with the vertices: A=(1,2) B=(-1,8) C=(7,10) a. find the midpoint M of Line Segment AB b. find the midpoint N of Line Segment AC c. Verify that Line Segment MN is...

Passes through (-1,7) and has a slope -5.

What is the eq of the line perpendicular to y=1/2x+1 that contains (-2,1)

So, I'm doing a math assignment where I have to make up an equation of a line in y=mx+b I picked y=2x+7 and now the next step is to find at least three other lines that are parallel to...

I got y=1. is that right?

The graph shows the lines 5x+4y=7 and x-3y=9. Based on the graph, estimate the solution of the system of equations: 5x+4y=7 x-3y=9

I don't know how to figure this out and get it into y=mx+b form. Any help is appreciated.

Determine whether the line through (2,4) and (6,1) is parallel to a second line through (-3,1) and (1,-2).

the full question on my homework sheet is: Describe the characteristics for a line to be parallel to another including both the slope and y-intercept. I just don't understand the y-intercept...

The slope of the line perpendicular to another line whose equation is 2y+ 3x - 4 = 0.

Create a line perpendicular to the line that goes between the points (-7,0) and (0,13)

(-7,-5) (-3,7)
