Answer:
Slope AB = -3/2
R = (4, -7)
Step-by-step explanation:
AB (-6 , 8) and (-2 , 2)
Slope AB = (8 - 2) /(-6 + 2) = 6/-4 = -3/2
Triangle QRS , QR is half of AB, same orientation and given Q (2 , -4) so R = (4, -7)
How to do the vertex is using the formula -b/2a
your a=-9 and b is -18 but it going to become +18 because you are multiplying the -(-18) which there a 1 in front the neg. you going to multiply the -9 by 2 and do 18/18 so your x= -1. You got your x, you going to put in the equation as y=-9(-1)^2-18(-1)-1 then you got your y... hope this is helpful :)
