Positive 2 is your slope, (rise over run) if you have to graph it and -1 is your y-intercept
Slope intercept form: y=mx+b
y-7= -0.75(x-12)
Distribute.
y-7= -0.75x+9
Add 7 to the other side.
y=-0.75x+16 <- that is in slope intercept form.
I hope this helps!

Mean- add all of them together and divide by the amount of numbers there is
3+5+3+3+8+8+9+9=48
48/8= 6
median- put them in ascending order and it’s the number in the middle
3,3,3,5,8,8,9,9= 6.5
the middle of the numbers is between 5and8. so do 8-5=3/2= 1.5 5+1.5
mode= most common number that appears = 3
range= biggest number take smallest number
9-3= 6
Y = 1/4x....slope here is 1/4. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, " flip " the number and change the sign. So the negative reciprocal for our perpendicular line is -4.
y = mx + b
slope(m) = -4
(2,-5)...x = 2 and y = -5
now we sub and find b, the y int
-5 = -4(2) + b
-5 = -8 + b
-5 + 8 = b
3 = b
so ur perpendicular equation is : y = -4x + 3
