Russian Math. Fun isn't it?
the answer is No Solutions
since absolute value is the distance a number is from 0. You cant have a negative absolute value<span />
It is not correct because the second answer tells you how far to go up and down, not across.
First, you want to find the slope of the line. You do this by taking the difference in the heights divided by the difference of the time.
m=(20-12)/(5-3)
m=8/2
m=4
Now plug the information into slope intercept form (you can choose whichever set of data you want, just as long as you are consistent):
y=mx+b
12=(4)(3)+b
12=12+b
b=0
This is saying that there is no y-intercept (b).
So our final equation is:
y=4x
The question is asking for y when x is 1, so just plug it into the equation:
y=4(1)
y=4
Hope this helps!
You should pick none of the above
