formula of making linear equation is (y-y1)/(y2-y1)=(x-x1)/(x2-x1) at last the ratio of x is the slope
1. -2/5 2. 0 3. -6/7 EXP: 1. (3-5)/(7-2)=-2/5 2. (-2--2)/(2-11)=0 3. (3-9)/(5--2) The formula is: (y2-y1)/(x2-x1)
The rule is : y2-y1/x2-x1 just substitute the numbers in the question in the rule and you'll have the correct answer
for example the first one will be : 3-5/7-2 = -2/5
so i tried what you said on this Find the slope of line passing through the points (4,8) and (6, -2). and got -6/2 which is -3 but neither option is there.
what did I do wrong?
show me what u did ...maybe u mixed up the signs
(4,8) and (6, -2) (2-8)/(6-4) -6/2
u forgot to put the - sign infront of the 2
ohhh Haha I get it now thanks!!!
Happy to help :)
okay so I feel really stupid for asking again... But I tried it on this one What is the slope of the line that passes through the points (–6,1) and (4,–4)? I didnt forget any - signs this time and
i got -3/-2 and thats not an option
the two -- are turned into a +
as u r writing it this way : -4-4/4+6=-8/10=-4/5
as if *
A.-2 B.2 C.-½ D.½ are my choices
sorry ...my mistake i wrote -4 instead of -1
here's the solution
it's c .-1/2
thanks I was sitting here going uhhh
urw....again srry for the mixup :)
