We know that
slope m=(y2-y1)/(x2-x1)
then
case a) x=18
m=(y2-y1)/(18-18)--------------> is undefined, because <span>the denominator is zero
case b) </span><span>2y-6x=0
2y=6x------------> y=3x
the slope m=3-----------> m is defined
case c) y=9
</span>m=(9-9)/(x2-x1)--------> m=0-----------> m is defined
case d) y=x
m=1---------------> m is defined
the answer is
x=18 has an undefined slope
Answer:
C
Step-by-step explanation:
I Used my eyes UwU
Value of 1.2^2=1.44
value of 2^3+17-3*4=8+17-12=13
value of 9^2/3^3= 81/27=3
-------------------
<span>x + 8 + 7 =7
x + 8 = 0
x = -8

Answer: LAST OPTION.
Step-by-step explanation:
In order to solve for the variable "x" from the expression , you need to follow these steps:
1) You need to multiply both sides of the equation by 3:
2) You need to multiply both sides of the equation by 6:
3) Finally, you can divide both sides of the equation by 15:
