Answer:
-¾
Step-by-step explanation:
Slope=m
(-1,9) (3,6)
m= Y2-Y1 / X2-X1
m=6-9/3-(-1)
m=-3/3+1
m=-3/4
Answer:
2.06×10^14
Step-by-step explanation:
nth term of G.p = ar^n-1
the first term, a = 3 common ratio, r = 2nd term/ 1st term, 3rd term/ 2nd term, etc.
r = 9/3 = 3
30th term = 3(3)^30-1 = 2.06×10^14

Step-by-step explanation:
x = 2 is, as you can see, parallel to the y-axis.
perpendicular to this (= crosses the original line in an angle of 90 degrees) is then a line parallel to the x-axis.
that means y is constant. all points on that line will have the same y value.
and we know one point already : (3, -2)
so all points of the perpendicular line will have y = -2
and that is the equation of the perpendicular line :
y = -2
