Answer:
you want to flip the original coordinates and make them both negative so (x,y) would become (-y,-x) so in your problem here Q' would be (0,-7), R' would be (-5,-8), S' would be (-10,-7) and T' would be (-5,-2). Hope that helped :>
Step-by-step explanation:
Answer:

Step-by-step explanation:
If A = (-3,-1) and B = (4,4), the slope of AB is

Two perpendicular lines have slopes that have product of -1:

The equation of the line BC with slope -1.4 and passing through the point B(4,4) is

Answer:
a-3b+4
Step-by-step explanation:
1/2 (2a−6b+8) =
=1/2*2a-1/2*6b+1/2*8
=a-3b+4
The plotted point will be reflected across the y-axis.
The fraction would be the portion over the total:
240 / 5280
Divide both top and bottom by 240 and the fraction simplifies to 1/22
The answer is 1/22
