What do you need help with?
For this type of equation, you will need to use point-slope formula [Y-y1=a(x-x1)] Lets work it out.
Y+3=1/3(x-9)
Y+3=1/3x-3
Subtract 3 from both sides so
Y=1/3x
Answer:
$20
Step-by-step explanation:
Because if $80 is originally 100%, the 80% is $60. So $80 - $60 = $20
Answer:
X2 = (-2, 1), W2 = (-4, 1), Y2 = (4, -2), Z2 = (-3, 2)
Step-by-step explanation:
First, flip across the y-axis:
Coordinates: X1 = (2, -1), W1 = (4, -1), Y1 = (2, -4), and Z1 = (3, -2)
Then, rotate 180 degrees counterclockwise:
Coordinates: See above
Ben is right, you must add 25 not subtract it
