(y2 - y1)/(x2 - x1) ^^^ Essentially says, subtract the y from y, the x from x. Y is over x. You just have to subtract them in the same order from x in the y. So you can't do 4 - -1 and then 2 - - 3.
4 - - 1 = 5 because subtracting a negative is adding a positive. -3 - 2 = -5
So your answer is -1. Because. 5/-5.. it's.. it's -1.
the slope of the line that passes through the points (x₁,y₁) and (x₂,y₂) is \(\frac{y_2-y_1}{x_2-x_1}\) given (-3,4) and (2,-1) (x,y) x₁=-3 y₁= 4x₂= y2₂=-1
subsitute \(\frac{-1-4}{2-(-3)}\) \(\frac{-5}{2+3}\) \(\frac{-5}{5}\) -1 the slope is -1
