Answer:
slope is undefined
ex. a straight vertical line like x = 2 would have an undefined slope
Step-by-step explanation:
formula is
y2-y1 / x2-x1
-13 + 9 / -5 + 5
-4 / 0
slope is undefined
straight vertical line like x = 2 would have an undefined slope
undefined slope is the slope of any vertical line that goes up or down. There is no horizontal movement and hence the denominator is zero while calculating the slope. Thus the slope of the line is undefined.

We could use Algebra for this question but it’s quite simile so won’t need it. If Amanda is 25, when we add on 5 years she’ll be 30. Now it says when she’s 30, she will be twice as old as Simone. Implying that Simone will be half of Amanda’s age. In this case 30/2 = 15. So Simone must be 15.
Answer:
Ali's salary is $50000.
Step-by-step explanation:
Let Jafar's salary be x.
(31/100)*x = 12400
x = (12400*100)/31
x = 400*100
x = $40000
Let Ali's salary be y.
y-[(20/100)*y] = 40000
y-(y/5) = 40000
(5y-y)/5 = 40000
4y = 200000
y = $50000
