I have a math problem and it is telling me to find the slope of a line or watever but i dont understand!!
Can you help me plz
Thank You

the slope of the line can be figured out with a simple formula. If the question gives you two points all you have to do is plug into the formula delta y over delta x. this means take the two y coordinates and subtract them from each other and divide that by the same thingy with the x coordinates.
For example. ( 0, 0) and ( 1, 2) What is the slope between those two points?
just do (2 - 0 ) over ( 1 - 0 ) = 2/1 = slope of 2
The other method is to draw a line between the two points and count the boxes (on graph paper) you first count to the left then up. so it would be starting from (0,0), you count 2 boxes to the left, then 1 up. that would be 2/1 which is slope of 2.

9) Given: the line with the help of (5,3y) and (2,y) is parallel to a line with slope 4 => the line with the help of (5,3y) and (2,y) has slope 4 => (3y - y)(5 - 2) = 4 => 2y = 12 => y = 6 question huge kind 14 and 15 have an same technique. attempt question no 15 your self 14) technique I : (y2 - y1)/(x2 - x1) = m enable (x,y) be an arbitrary element on the line .·. (4 - y)/(2 -x) = 2 => 4 - y = 4 - 2x => y = 2x technique II: enable y = mx + c be the equation of the line all of us recognize that x = 2 .·. y = 2x + c (2,4) is a level in this line. .·. 4 = 2*2 + c => c = 0 => line equation is y = 2x

it depends on what kind of slope your teacher is looking for. draw a line. measure the rise, and the run. slope can be like a 4:12, meaning it has a rise of 4, and a run of 12, or it can be 3% as in 3% of 90 degrees (straigt up is 90 degrees), or it can be in degrees.
good luck.

Y1-Y2/X1-X2
or just plot the points on a graph and draw a right angle between them. Then see how many places you go over (run) and up or down (rise). With this in mind, put the rise over the run, like a fraction. Oh by the way, if you go left on your triangle, that is a negative run, and the same goes for the rise.

Not sure what your question is.. to find a slope.. draw a line between the two lines and with a graph, determine the slope in degrees.... easy

you can use the confusing method when you subtract the points or you can connect your two points then calculate rise over run (rise/run)... this is the easiest way to find the slope....
If you give us the 2 points then we can give you the answer

slope equals (y2 - y1) divided by (x2 - x1).
Your two points are (x1, y1) and (x2, y2)
