Write an equation of the line that passes through the points (-3,4) and (-5,1).
You should first find the slope and that would help alot y2-y1/x2-x1
So what would the slope be?
-6?
okay so \[\frac{ 1-4 }{ -5--3 }\]
-3/-8
-3/-2
yes so that becomes 3/2 because the negatives cancel each other out
Next you need to do point slope form y1-y=m(x-x1)
do you understand?
@stefrheart be careful with the slope formula. the direction is important the change in y / CORRESPONDING change in x y1 -y = m( x1 - x)
No I am correct @triciaal on the formula that the y goes first
@Stefrheart you clearly misunderstood what I wrote!!! even look at what you posted which is correct and the same as mine. the coordinates are (x, y) and (x1, y1) same direction/ corresponding y - y1 x - x1 using (y x ) (y1 x1) what you had was from above " Next you need to do point slope form y1-y=m(x-x1)" you have y1 - y x - x1 using (y1 x) and (y x1) can you see it now ? if not plot the points and review for a second.
