do u know how to do this??

alyssa_xo · Answer

use the slope formula $\huge m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}$

texaschic101 · Answer

slope formula : (y2 - y1) / (x2 - x1)
(-1/4, 3/4) ---- x1 = -1/4 and y1 = 3/4
(1/2, -3/4) --- x2 = 1/2 and y2 = -3/4
Now sub
slope = (-3/4 - 3/4) / (1/2 -(- 1/4)
slope = (-6/4) / (1/2 + 1/4)
slope = (-6/4) / (2/4 + 1/4)
slope = (-3/2) / (3/4)
slope = -3/2 * 4/3
slope = - 12/6
slope = -2

@texaschic101  i'm a little confused with where the addition came in

alyssa_xo · Answer

subtraction of a negative = positive
1-(-3) = 4

you can view it as the negatives "cancelling"
