The slope of line T is -1/5, because perpendicular lines have opposite reciprocal slopes, meaning the opposite sign (positive or negative) and flipped (whole number becomes a fraction).
BC = √[(8-1)^2 +(1-6)^2]
BC = √(49+25
BC = √74
BC = 8.6
answer
8.6 units
The slope is 4 and the Y-Intercept is 0.
Answer: D' is (-8,4)
Step-by-step explanation: The rule for reflection y=x is (x,y)>( y,x) So when relecting over the axis y=x the x cordinate and the y cordinate switch places.
