Asked by unknown

Krystina is trying to derive the slope of a line with coordinates (6,-2) and (0,8) using the formula △ y/△ x =frac y_2-y_1x_2-x_1. Krystina says the slope is (-3)/5 because slope = rise/run =frac x_2-x_1y_2-y_1= (0-6)/8-(-2) = (-6)/8+2 = (-6)/10 . Is Krystina's calculation for slope correct? If not, what is an appropriate explanation for why she is incorrect? (1 point) Yes , it is correct No, it is not correct, She has rise/run as change in x / change in y No, it is incorrect, that is the midpoint formula

No — it is not correct. Krystina computed Δx/Δy instead of Δy/Δx.

Correctly,
m = (y2 − y1)/(x2 − x1) = (8 − (−2))/(0 − 6) = 10/(−6) = −5/3.
